Dickerson and a final salute to the the Big Bang Theory. I will miss hundreds of people working together to create something, which is always the most magical part. Dickerson good evening. Im john dickerson. This is our western edition. It is a battle being fought on more than a dozen fronts, the battle over abortion rights. Tonight, missouri appears to be on track to pass a bill that would ban abortions at eight weeks of pregnancy. Missouri would thus join 14 other states that have enacted abortion bans or restrictions this year. Adriana diaz reports. This is an unconscionable use of our power. Reporter after missouri lawmakers battled through the night. The time of choice is the time of conception. Reporter . The state Senate Passed a bill that would outlaw abortiontes, around the time a heartbeat is often detected. The ban applies to cases of rape and incest, but makes an exception for medical emergencies. Doctors who perform abortions after the cutoff could face up to 15 years in prison. Missouri only has one Abortion Clinic left. This planned parenthood in st. Louis. Antiabortion activists outside the clinic call the senate vote a victory. What do you make of the Senate Passing this bill . Were always excited when we see more prolife legislation passed. Reporter but inside, theres outrage. Im furious. Reporter Kawanna Shannon is the director of surgical services. This bill, if turned into law, will allow women to have abortions earlier on. Do you think thats not enough . A lot of women dont find out until theyre already passed that time. Reporter dr. David eisenberg is the medical director. Do you feel that now we are in a moment where roe v. Wade really can be overturned . It doesnt really matter whether roe v. Wade is the law of the land as it is now. When individual states can do what theyre doing, which is regulate abortion out of existence. Reporter missouri joins 14 other states that have proposed socalled heartbeat bills in 2019 alone. Four states have signed them into law. Just yesterday alabama passed a neartotal ban on abortions, the most restrictive law in the country. Antiabortion organizer kathy forck hopes missouris bill will create a path to overturn roe v. Wade. We care about these women. We want them to be safe, and i think that the legislature is doing everything they can to keep these women safe. Reporter the bill here in missouri is expected to pass the house and the governor has already pledged to sign it. John, a cbs news poll found that most voters nationwide believe that abortion in some form should be available, though 22 believe it should not be permitted. Dickerson adriana diaz in st. Louis. There is breaking news in Southern California. A plane, possibly a jetfighter, has crashed into a building in riverside. Heres the latest. Reporter the fighter jet plunged inside a warehouse late this afternoon. Thats a military airplane in our building. Reporter eyewitnesses say the f16 fighting falcon pancaked on to the roof shortly after taking off from a runway at the march air reserve base. The pilot ejected before the plane went down, and remarkably, there were no reported injuries inside the warehouse. Reports say live ammo was on the aircraft at the time of the crash. Jonathan vigliotti, cbs news, los angeles. Dickerson President Trump today tried to jump start the process of overhauling americas Legal Immigration system. No president has been able to do that for more than three decades. Mr. Trump wants a point system for wouldbe immigrants. Those with skills or Higher Education would score higher in that point system. Democrats say it doesnt add up. Heres paula reid. We are proposing an immigration plan that puts the jobs, wages, and safety of American Workers first. Reporter the proposal emphasizes new security measures at the border and a shift to a meritbased Selection Process for legal immigrants. If you want to become an american citizen, it will be clear exactly what standard we ask you to achieve. It will be made crystal clear. Reporter the president s plan would favor younger applicants with specific skills or Higher Education who can speak english and pass a civics exam. The Current System admits mostly people with relatives already in the u. S. A big proportion of those immigrants must come in through merit and skill. Reporter House Speaker nancy pelosi objected to how the plan defines merit. It is really a condescending word. Theyre saying family is without merit . Are they saying most of the people who have ever come to the United States in the history of our country are without merit . Because they dont have an engineering degree . Reporter the plan does not address the pressing challenge of the 11 Million People living in the u. S. Illegally, or the socalled dreamers, people who were brought to the country illegally by their parents. Democrats wont support a plan that does not address those issues. This sham proposal is dead on arrival. It is a mockery of what america means. Neither Donald Trumps grandfather nor my father would be able to come to america under this proposal. Reporter some republicans say theyre disappointed this plan would not reduce Legal Immigration and would continue to issue about a million visas a year. In response to all this blow back from capitol hill, a Senior Administration official says this is just an opening offer. John. Dickerson paula reid at the white house. President trump lowered the temperature today on possible conflict with iran, but the American Military buildup in the Persian Gulf Region continues. As we learn more about reported iranian threats against the United States. David martin is at the pentagon. Reporter the Carrier Strike group headed by the u. S. S. Lincoln has arrived in the arabian sea south of iran just as President Trump tried to calm fears the u. S. Is on a path to war. An aide to acting defense secretary shanahan said the president has told him he does not want war with iran, a message he repeated in public to reporters. Mr. President are, we going to war with iran . Hope not. Reporter earlier in the day, the president had tweeted, im sure that iran will talk soon. That might ease war jitters, but it does not solve the problem of u. S. Intelligence warnings iran is preparing to attack americans based in iraq. Those warnings began with an israeli intercept of an iranian commander ordering militias he controls in iraq to make preparations. In an interview with face the nation moderator, margaret brennan, irans ambassador to the u. N. Denied it all. Fake intelligence, which has been the root cause of all these events, should be tackled. As soon as we get rid of these fake intelligence, all of us will be in a much better situation. Reporter u. S. Intelligence also has Satellite Photos of the iranian port of chabahar, which show what analysts say are containers for shortrange Ballistic Missiles loaded on boats for transport to an unknown location. The u. S. Warnings got some backup from a key ally today when the British Foreign secretary tweeted, we share the same assessment of the heightened threat posed by iran. John. Dickerson david martin at the pentagon. New york city mayor bill de blasio joined the race for president today, making it an even two dozen candidates seeking the democratic nomination. The mayor, 65 tall, and the current president , 63, have sparred before, but today the gloves came off. Heres ed okeefe. Donald trump must be stopped. Ive beaten him before, and i will do it again. Reporter new york mayor bill de blasio is hoping to trade city hall for the white house. Well, i intend to break the mold, and i intend to make history, and i intend to win. Reporter but more than seven in 10 new yorkers say he shouldnt run. You cant run the country you cant run the city. Reporter members of the police union protested at his times square announcement, a hometown newspaper laughed at his prospects, and a famous fifth avenue resident mocked him as the worst mayor and a joke. De blasio joins a record breaking field 14 current and former members of congress, three current and former governors, two other mayors, a former cabinet secretary, a business executive, a selfhelp author, and former Vice President joe biden. applause he maintains a commanding lead, and now some rivals are starting to target him, like california senator kamala harris. Touted by some as a potential running mate, this week she said it should be the other way around. I think that joe biden would be a great running mate. Reporter and if two dozen candidates isnt enough, former Georgia State lawmaker Stacey Abrams is still teasing she might get in. I do believe i can enter the conversation as late as the fall and still have a real chance to win. Reporter the sheer size of the field is leaving some voters overwhelmed. Its a lot. Thats a for the democrats alone . Wait, i thought this was, like all the parties. There are many that i just cant i cant even relate to. Outrageous, ridiculous, a losing cause. Reporter at least for some democrats, less might be more. Ed okeefe, cbs news, washington. Dickerson we are beginning to see fallout from the escalation of the trade war between the United States and china. Last friday, President Trump raised tariffs to 25 on nearly 6,000 categories of products from china. Tonight, three correspondents look at this from different perspectives in the u. S. And in china. Reporter this is Ramy Inocencio in beijing, where the escalating trade tensions are spilling over into state media from commentary on tv, vowing to fight, to propaganda on social media taunting the u. S. To bring it on. The message is clear beijing is ready to push back. And chinas citizens are picking it up. Do you think beijing should push back against washington, d. C. . As president xi and chairman mao said, you cant have lasting peace without war. We feel america is a bully. All of this a reaction to the increased tariffs on 200 billion in goods the chinese ship to the u. S. Victor gao is an expert on International Relations in beijing. To what degree can washington, d. C. Hold down beijing . No one in the world can really launch a trade war against china and win that trade war. Reporter a reminder there will be pain on both sides. Reporter im Dean Reynolds in elkhart, indiana. Does the president understand tariffs . I better im hoping im thinking he does. Reporter businessman tom irions says the pain from tariffs is getting worse by the day. President trump, we support him, but this idea of tariffs being paid by the Chinese Government is something that i dont quite understand. Reporter irions firm Asa Electronics manufactures systems for pleasure boats, r. V. S and commercial vehicles. 110 workers here assemble the parts made by 2,000 contract employees in china. Its a 100 million business. If the president makes good on his threat to further expand tariffs on chinese imports, the price of one of irions premium systems could increase by 1,000, and the people who will pay are his customers. The trade war has created something businessmen just hate. Uncertainty. Uncertainty. Reporter im Jonathan Vigliotti in Southern California where that uncertainty is also threatening common household products, like those at speers tv, family owned for nearly three generations. I walk into your shop, and i say, show me your u. S. Made televisions. Which ones would you show me . Youre going to have to go back 20 years, 30 years. There are no more u. S. Made tvs anymore. Reporter Alen Harikian runs his sales and repair shop with his father. So these tariffs could hit your bottom line here. Yes, absolutely yes. Reporter in fact, the tariff on all chinese goods could cost the average family of four up to 2300 a year. Those higher costs could mean a shift in how harikian does business. Well you have to try to do other things i guess. Try, you know, installation, laborwise. Maybe repairs are going to go up because people are going to not buy a new tv because the price is higher, so they might end up repairing it instead of buying it. Reporter and whether the impact of the tariff is felt in beijing, elkhart, indiana, or here, experts we spoke with say in an escalating trade war, everyone loses. John.

Dickerson wars in iraq and afghanistan have left hundreds of thousands of veterans and activeduty Service Members struggling with traumatic brain injury. Even mild cases can have lasting effects. Dr. Jon lapook tells us about a possible new treatment. Reporter in one month, Sergeant MajorRodney Rhoades will retire from the army, where he spent 32 years serving in places like somalia and iraq.

What we saw were improvements in in attention and memory, largely. It didnt take me from back to where i was, but it gave me improvement, which i appreciated. Reporter these are early days for this type of treatment.
