Reporter doctors saying he continues to improve after a delayed acknowledgement that his oxygen levels had dropped twice in recent days and that hes now taking a steroid typically only recommended for seriously ill patients in the hospital. They may be thinking that they can turn the white house into a bit of a hospital for him. But if he needs intensive care unit, hes going to have to go someplace with a great team. Its a very, very serious disease. Reporter at the same time, questions remain about the scope of the outbreak inside the white house. Press secretary Kayleigh Mcenany and two top assistants today joining the list of several highlevel staffers testing positive. Even though President Trump is now back at home, you heard his doctors say that hes not out of the woods yet, and he is certainly going to need to be closely monitored because medical experts agree that the next few days in the course of any covid19 diagnosis are critical for recovery. Back to you, jessica and raj. Thank you very much, alice. Now, as we told you, the president is going to continue his treatment and the recovery portion at the white house. The question is, is that a good idea . Lets bring in our janelle wang, who spoke with our Infectious Disease specialist about this decision. So what did dr. Peter chinhong have to say . Yeah, dr. Peter chinhong of ucsf says its not unusual a covid patient is discharged fairly soon after being diagnosed with covid, especially if theyre doing well, which is what the president says hes doing. Hes feeling very good and especially since the president has a full medical team at the white house. But its the president s treatment thats sounding some alarms. The president received what dr. Chinhong calls the dream trio, an antibody cocktail similar to convalescent plasma, remdesivir, and the steroid dexamethasone. That combination is usually given to the sickest patients. Dr. Chinhong says the antibody cocktail and remdesivir not really any serious consequences if you take it. But dexamethasone, thats baffling. Is it harmful for somebody who has mild symptoms to be taking the steroid . So unlike convalescent plasma or an antibody cocktail, using steroids come with some side effects. So the side effects are its an immune suppressant, so you can imagine why biologically it wouldnt make sense to give it early on because youre trying to have the immune system not sleepy so that it can try to mop up whatever virus it could. Secondly, it can cause more infection superimposed because its an immune suppressant. So we worry about when you do something and the risk benefit calculus supports not using it, that using it prematurely may end up being worse than the benefit it was supposed to get. Dexamethasone also has side effects including euphoria, which some people enjoy but patients can also become manic and suffer other Mental Health side effects. Dr. Chinhong says the key now is that the president be closely watched because Covid Patients can take a turn for the worse pretty quickly, and the president should also isolate himself. We tell them they cant really go out into the world really because theyre still potentially shedding infectious virus. And the cdc actually has very good guidance around this. So the minimum is ten days before having Infection Control precautions be disbanded, and 20 days if youre really sick. Dr. Peter chinhong a little disappointed that the president downplayed his covid diagnosis on twitter since covid19 has killed more than 200,000 people in the u. S. So far this year, and things expected to get worse with flu season now here. Doctors are calling it the twindemic, so its important, dr. Chinhong says, to get that flu shot as we wait for a covid vaccine. As for the president , its wait and see. Dr. Chinhong says the next few days still very dicey and doctors should keep a very close eye on him. Thank you very much, janelle. Meanwhile democratic president ial nominee joe biden is on the campaign trail tonight in miami. Biden continued to wish the president and the first lady well as they battle covid19. Biden also urged President Trump to require all americans to wear masks in public. I would ask him to do this. Listen to the scientists [ applause ] support masks. Support a mask mandate nationwide.

In the wake of the death of george floyd and the National Reckoning on race, prosecutors are taking another look at what led up to his death and if other officers should have been charged. The stunning announcement came just as grants family was speaking to reporters at the b. A. R. T. Station where grant died. Nbc bay areas melissa colorado joins us from there with reaction from oscars mother and his uncle. Reporter we know it was a bullet from former b. A. R. T. Police officer johan es mezerlys gun that ultimately killed oscar grant, but now the family of oscar grant is saying oscar could have died the same which that george floyd did when a separate, different officer kneeled on top of his head and his neck. And now the family is calling on the District Attorneys Office to reopen the case. Oscar couldnt breathe. He announced he couldnt breathe several times. Reporter justice delayed is justice denied. That was the message from oscar grants mother, wanda johnson, and grants uncle Cephus Johnson today during a press conference outside of the fruitvale b. A. R. T. Station. Youll recall a jury convicted former b. A. R. T. Officer johan es mezlerly of involuntary manslaughter. The grant family says it was another officer on the scene, anthony perotny, who also deserves his day in court for felony murder charges because video from the scene shows pirrony kneeling on oscars neck and head. Youll see the same tactics that was used on george floyd was used on my son oscar. Just like in George Floyds case, we can see how it can happen very easily that oscar would have suffocated under 250 pounds of weight that was on his neck. Reporter the family points to a b. A. R. T. Internal Affairs Investigation that blasted pirrony for unnecessary use of force and his use of the nword while arguing with grant. In the middle of the press conference, grants uncle read out loud the news the family was praying for. Alameda County District attorney Nancy Omalley is reopening the investigation. And make a determination. [ applause ] reporter omalley says, quote, i have assigned a team of lawyers to look back into the circumstances that caused the death of oscar grant. We will evaluate the evidence and the law, including the applicable law at the time and the statute of limitations and make a determination. Were not holding our breath, but we definitely will be praying. Reporter in oakland, melissa colorado, nbc bay area news. Up next here at 5 00, there is progress in the north bay.

Cal fire posting this video on twitter of a super tanker dropping retardant at Robert Lewis Stephenson state park in napa county. The fire destroyed hundreds of houses and businesses. That map shows the extent of it. Yellow means repairs are needed. Red means the structure is destroyed, and unsafe to be in. So far more than 65,000 acres have burned. At this hour, this fire is 30 contained. 242 structures damaged. More than 1,200 destroyed. Nbc bay areas Jodi Hernandez joins us from calistoga with the very latest. Jodi. Reporter jessica, downtown calistoga is finally starting to reopen as folks get the allclear to return home. But this area isnt out of the woods quite yet. But its heartbreaking. It really is. Reporter eric stretic spent the morning trying to take in whats become of the property hes been taking care of for the last three decades. Nicknamed the quail cottage, the calistoga home was totally leveled by the glass fire. Im in shock. It hasnt fully sunk in. It really hasnt. Its just almost too much to process. Reporter after nearly a week, most people in calistoga are finally able to come home. While the glass fire is still burning north of town, its safe for those in the city limits to return. We really thought that, you know, this was it. Reporter Jenny Wishart feared she wouldnt have a house to come home to. Shes so grateful. Very good to be back. Relieved to see our place is still standing. Reporter businesses are reopening in downtown calistoga. The silverado pharmacy has a lot of orders to fill. The folks who run it say they too feel lucky. We werent sure if it was going to burn or not, so we just took out the medications that we could save. Reporter but a lot of homes and businesses in the area werent as fortunate. The fire has destroyed some landmark spots, including several wineries and the popular greek macedonian park, where hundreds of bay area greekamericans gather for celebrations. While the grounds were destroyed, miraculously the chapel is still standing. Firefighters still have a huge task in front of them, but theyre starting to get a handle on things. They are working very hard. Imagine it was close to 100 degrees over the weekend. Reporter folks here are trying to focus on the positive as they move forward. Im happy to see the vineyards. Theres some greenery and some life still in the neighborhood. Reporter and were back here live. Youre looking at downtown calistoga. Not all of the businesses have reopened quite yet, but slowly but surely, we are seeing businesses start to resume their operations here. Now, the county has also set up a local assistance center. That opened this morning. That is located in napa at the county health and Human Services campus there in napa. That will be open six days a week to help families and businesses impacted by the glass fire. Reporting live in calistoga, im Jodi Hernandez, nbc bay area news. So many fires, yes. Thank you, jodi. We want to go back to our coronavirus top story. The president having left walter reed medical center. The president tweeted a message just moments ago from the white house. As we showed you, he was at the top of the this newscast, the president left the hospital about an hour ago and returned to the white house. I stood out front. I led. Nobody thats a leader would not do what i did. And i know theres a risk. Theres a danger, but thats okay. And now im better, and maybe im immune. I dont know. The president taped this message just after he got off of marine one. The president also encouraging americans who are battling the virus to, quote, not let that dominate them, saying that he that they will be beat the virus. As the president battles covid19, there is a concern about a second covid wave, especially with the halls coming up and flu season. Take a look. California numbers arent decreasing as fast as they have been, but theyre not going back up either. So its a pivotal time here. Heres the states Positivity Rate. Thats the white line right here. The Positivity Rate at 2. 8 . It dropped through the month of september. For the past couple weeks, the Positivity Rate started to plateau. As of yesterday, 2. 8 . Thats a pretty good number. Also more people are getting tested. Thats the next line, the blue line. You see the number of tests there per day. It started to dip a little when the wildfires started, but then testing heres the dip with the wildfires. Testing then went back up a bit. The numbers show more than 140,000 daily tests statewide. Jessica. Santa clara county could be just over a week away from relaxing its strict covid rules. The state could know by tomorrow if Santa Clara County will graduate from the red to the orange tier. If so, changes would take effect no earlier than october 14th. The most significant change would be Indoor Dining and public gatherings. Today the county announced dining and gathering would be capped at red tier levels. That means 25 of capacity or 100 people, whichever the number is lower. San francisco has already done it. San francisco is taking a similar approach where Indoor Dining and indoor gatherings for church and indoor Movie Theaters are also at the red tier level. Theres another message, which is that if covids cases spike again in the south bay as they did from june to july, then the county could revert to outside dining and other previous restrictions. Lets bring in our chief meteorologist jeff ranieri as we kick off this monday. Some good news in the north bay as you forecasted. What comes next week, jeff . We do still have two different chances of rainfall coming our way as we head through this week, so something to look forward to in that Weather Forecast finally. So i did want to start off with a wide view of what im tracking right now. And the other thing is going to be some remnant moisture from hurricane marie. Were going to see this stream of subtropical moisture just to the south of us the next couple of days. Our chances are slim of getting any rainfall from that, but any rain that gets close, we will be tracking it. Our better chances, i definitely think, of getting some rainfall are from two different storms, one on friday and one on saturday. Not only a rain chance but also some much colder temperatures. So lets go ahead and move it into tomorrow morning. No rainfall just yet. Well have 50s here to start with. Those areas of smoke, also some patchy fog near the coast and the bay. Right here for the east bay, 55. San francisco, 54. Some of that fog. For the north bay, 51. Overall numbers tomorrow drop a couple of degrees, so down in the south bay it will put us at 82 in san jose. 88 in gilroy. For the east bay, also still finding some upper 80s and low 90s. But as you head closer to the bay, numbers are beginning to drop down to 76 in oakland. Plenty of 70s through the peninsula as well for redwood city and palo alto, well be in the upper 70s. San francisco will be dropping into the 60s. Winds out of the west at 13. 69 here in the mission and the north bay, i have you coming in at 86 in napa. 84 in santa rosa. So tomorrow is dry with those areas of smoke, unhealthy air quality. But lets get to the good stuff. The big weather headline, and that is the potential of rainfall. So i want to fastforward things right into thursday night at 9 00 p. M. You can see how that storm system will be lining up right here at the coastline. Then as we move into friday, well see the rainfall at this point likely move over for the morning, and you can see. Then as we head through friday midday in the afternoon, well have some spotty rainfall left for us. Maybe even some snow across the summit near yosemite. Great news on that front. And then well see a second round of potentially some rainfall lining up once we hit saturday morning. And then that would be moving in as we head through saturday evening. Now, totals on this not very impressive right now, but well take anything we can get for that fire danger, right . 0. 05 to a half inch. Better bet of those higher totals in that yellow color right there through the north bay. Were done with the heat. Temperatures drop into the 60s this week with that chance of rain friday and saturday. Thats for San Francisco. And for my inland valley forecast, this is going to feel chilly for us. That is 72 on friday, 71 on saturdays forecast. Now, we still need to wait on some more information on these totals. Were definitely going to nail it down a lot more as we get closer. But the best bet right now, 0. 05 to about a half an inch on average. This is just what the firefighters need, especially the folks in the north bay now, so good news. We love that fall weather. Its so great to see that, especially when it starts to get a little chilly in the air, jeff. Up next here at 5 00, regal cinema shutting down all of its theaters indefinitely. Why they say they just cant continue to operate during this pandemic even though many counties are allowing them to open. In the bay area, we believe in science. Traffic and air pollution will be even worse after the pandemic. Thats why we support measure rr to keep caltrain running. Which is at risk of shutdown because of the crisis. To keep millions of cars off our roads, to reduce air pollution and fight climate change. And measure rr helps essential workers like me get to work and keep our communities healthy. Relieve traffic. Reduce pollution. Rescue caltrain. [all] yes on measure rr. The unfair money bail system. He, accused of rape. While he, accused of stealing 5. The stanford rapist could afford bail; got out the same day. The Senior Citizen could not; forced to wait in jail nearly a year. Voting yes on prop 25 ends this failed system, replacing it with one based on public safety. Because the size of your wallet shouldnt determine whether or not youre in jail. Vote yes on prop 25 to end money bail. Vote yes on prop 25 to wear a mask out in public around other people. Sure itll keep you healthy. But more importantly, i wont have to see your happy smiling face. Ugh. And if you dont want to wear a mask, ive just got one thing to tell you. Scram, go away. Ugh. Caring for each other because we are all in this together. So wear a mask and have a rotten day, will ya . Ugh. The august complex fire burning in Northern California has become the first gigafire in the state in decades. It started out as 37 separate fires in Mendocino National forest and spans seven counties. So far its burned a million acres, which is bigger than the entire state of rhode island. Take a look. This graph shows the top 20 wildfires in california since 1932. The red on your screen there represents the august complex fire. The burn area is larger than all of the other recorded fires between 1932 and 1999. The second largest Movie Theater chain in the u. S. Will go dark this week. Regal cinemas will temporarily close more than 500 u. S. Theaters starting thursday. About 40,000 workers will be furloughed. The move comes after the producers of the new James Bond Film delayed the release of the movie until april. That was the last major blockbuster on the schedule this year. Theater operators say theyre also being hit hard by the fact that theaters in new york, los angeles, and San Francisco were never allowed to reopen. Were back with more in a moment.

Im kate snow in for lester tonight whens hosting a town hall. President trump arrived back at the white house tonight and every moment was clearly orchestrated to send a messe. The president drawing criticism after this moment when he walked up to a balcony and then removed his mask. Then shot a cam panestyle video that has just been released in which he thanked his doctors and said he learned so much about coronavirus telling americans dont let it dominate you, dont be afraid
