he was once banned from twitter for so-called hate speech. berkeley is considered the birthplace of the free speech movement. yiannopoulos said the riots show the left wing doesn't support free speech. there were also peaceful protesters. no word on any arrests yet. closer to home, the 2017 missing mammal mystery has been solved. ollie, the national zoo's beloved bobcat, has been found. >>

visitor to the zoo this morning. >> reporter: zoo staff think she escaped through a gap in the enclosure's netting. that has been repaired. people living nearby were candor warned to keep an eye on

>> reporter: her escape captured dc's imagination. >> i was at work today, and it took me 30 seconds to realize we weren't talking tiger, we were talking cat. >> i was a little scared but then i found out they were only like this big. >> reporter: we've learned t own around here for some time. bobcats are native to this area. the greatest concern was that she might have an unfortunate encounter with a car, and very likely that did not happen. live at the national zoo, jackie bensen, news4. >> what a relief, she's okay. thank you, jackie. new at 11:00, a dump truck hit and killed a man using

publicly joined the 48 democrats opposing betsy devos. that would make it a 50/50 vote. if one more republican votes no, her nomination sinks. if it stays 50/50, then vice president mike pence would break the tie in her favor. republicans moved quickly today to advance the nomination of judge neil gorsuch to the u.s. supreme court. already there are signs he could face a tough path to confirmation. democrats are upset that the republican-led senate never gave judge merrick garland a hearing. he of course was president obama's nominee. now they're threatening to make trouble for gorsuch. but senator tim kaine says he will get a hearing. >> i can guarantee this. the democrats, we will have a hearing, and there will be a vote on judge gorsuch. but he's got to get to the 60-vote threshold. we allow people to be confirmed for any position, a with 51 votes, except the supreme court justice. and as we all agreed to that because a supreme court justice should have to meet a higher standard. >> a study by three supreme court scholars places gorsuch farther to the right ideologically than the late justice antonin scalia. his confirmation hearing is set to begin in six weeks. they went fast. the national museum of african-american history and culture released timed entry passes for the month of may today. the online system had some problems again, but all 114,000

commercial without crying. for others, it fell flat. this bud's no longer for me. it's activist juice. but for its part, budweiser says its ad was a year in the making, adding, we did not set out to create a piece of preliminary commentary. however we recognize you can't reference the american dream today without being a part of the conversation. >> i do not think you're going to see a lot of politics in the super bowl this year. people would like to take a break and enjoy the super bowl, enjoy some ads that they find, you know, either humorous or nostalgic. >> reporter: another brand, weather tech, will air an ad touting its made in america products, another issue in the news. but from the brewery that gave us singing frogs, puppies, and of course clydesdales, a taste of the past

sunshine, clouds. we've been all over the place, and it's only wednesday. what next? >> the same. you name it, just about everything in there that you named, we're going to have over the next couple of days here, right on into the weekend. we've got some mild temperatures, cold temperatures, a chance for a little bit of snow, a chance for rain, a couple of other things too. out there now, a nice mild night. if you're just getting back in from taking the dogs for that walk, before you had to come and check out the winds out of the north at nine miles per hour. that northerly wind will bring the temperatures down. so will the clearing skies. 42 in warrenton. temperatures now are still about average or even above average for this time of year for high temperatures. as far as the rain is concerned, most of this is not hitting the ground. we'll stay dry tonight. one thing i'm watching, not much going on across the country here. but we are tracking this area. you can just kind of see the flow here. what that flow is, is some cooler air that's going to try to make its way across our region. tomorrow we'll feel cooler. it will be 49 degrees, partly cloudy. cool and breezy. that breeze gusting 15 to 25 miles per hour at times. it will make it feel like windchill will be in the low 40s. it's going to be a little bit on the chilly side, especially in northwest zones. tomorrow morning, cool, 38 begs. cool in the afternoon with the 49 degree temperature, north and west a little bit cooler. down to the south maybe warmer, some areas might hit 50. next couple of days, 41 on friday. friday is a cold day. windchills in the 30s all day. saturday, even colder. high temperature on saturday of 38 degrees. it's still going to be rather windy on saturday, maybe 10 to 20-mile-per-hour winds. 38, sun and clouds, breezy. windchills on saturday in the 20s. they could start in the teens early saturday morning. that's going to be a cold day. that's really it. 45 is what we're going for on sunday. sunday is still a lot of questions with this forecast. one thing's for sure here. take a look at this. calling 30% chance. this is a very weak system. that's something that i know for sure, this is going to be a weak one, not going to be a big system at all. i'm thinking flurries to the north, sprinkles to the south. no road issues. i am not anticipating any road issues at all. but could we see an hour or two of snow? that's something that i'm watching here, some of our northern zones. it will still be warm enough that anything would melt on those roadways. 47 degrees on monday. look what happens next tuesday and potentially heavy on tuesday into wednesday. 63 degrees for high temperature wednesday. this storm system again has a lot of question marks too. does it stay on the warm side or does it bring in some colder air? we'll have to wait and see about that as well. it does look like it will be a little colder behind us. this forecast is very, very tough. i've been wracking my brain back there. it's got to continue like that. sometimes you like nice tranquil weather whethre it's easy to forecast. this one is tough. >> that's why they pay you the big bucks. >> thanks. coming up, a redskin starts campaigning for his quarterback. plus the caps keeping up with the wizards. >> sports is next. first, here''s jimmy fallon. we have music from the my

the rebound. 14th of the season. capitals just out 2-0 now. second period, bruins come back to even things up at 2. the power play, alex ovechkin fires and scores from that i favorite spot, his 25th
