jonathan: we are trying to get a better ideas of what is happening outside the arena. there is only a handful arrests so far. no real violence. but there has been tension and confrontations. there are representatives from black lives matter and westboro baptist church and from the ku klux klan all outside. keep in mind outside the arena there is an area where people can protest. they are outnumbered by police by 3:1. the police presence is significant. they knew going in the convention they would have to arrest some people because some protesters would get out of hand. this protest this afternoon, people were clashing, some yelling going on. you see people lying in the street. we haven't heard of violence. we have only heard of a handful of people getting arrested. up until this there had been only five arrests complete. one was for outstanding warrant. a couple of people tried to

banner and they got arrested. no violence. just mischief. this is the first sign we have seen but as you can see the protesters are outnumbered by police 3-1. they have a ring around the arena. we will continue to follow what is happening outside the arena. go live to the chief political correspondent scott thuman. we will have him in a few minutes. he is inside the r.n.c. for day two. meantime, back to you. leon: thanks, jonathan. we are going back out to breaking news coming in from prince george's county. drivers are urged to avoid b.w. parkway. there is a crash there. landscaper critically hurt in a crash on the northbound side. the traffic is diverted off the parkway to route 410. the southbound lanes are slowing down for several miles as the people slow down to make their way around the site and rubber neck. we will keep you posted on what happens there. another challenge for the metro riders to deal

in a -- vol tan fluctuates. the on board computers will turn off the hvac system and then require a reset before the air can continue. the cars are all under warranty. the manufacturer is here it at metro working to address the issues quickly. riders saying having issues the the new cars so soon is frustrating. >> i was dry when i got on the car. now i'm sweating. pouring. i mean for a person not in good health, i'm okay. imagine someone that is old, elderly person not in good health. they are in trouble. easy to succumb to something on the train on metro. brianne: metro says with the majority of the 7000-series rail cars the hvac system works great. we found that as well. 72-75 degrees using temperature gauge on board the train. metro wrk

the manufacturer is working on a software upgrade to make sure if there is a needed reset because of the fluctuating voltage in the rail car the a.c. will stay on while the reset is happening. reporting live, brianne carter, abc7 news. leon: all right. thanks. speaking of the heat we have a break from the steamy weather. doug? doug: the temperature is warm. 91. but the key here is the dew point is 63 degrees. getting drier. not as processively hot and humid -- progressively hot and humid. through the evening, weather is fine. first pitch in an hour at national park. dodgers are in town. beautiful weather. drop in 80's with a breeze and partly cloudy skies. the showers and the storms continue to move far south of the region through southside virginia. that will be that. several days of sunshine. citi open forecast for the whole metro area tomorrow beautiful start to the day. get up to 87 for the high. that is comfortable. low humidity. later in the week one of the

to think she would be doing anything that would be unnoticed is absurd. leon: what do you think? do you think melania trump plagiarized her speech? wjla.com/votenow. most folks say yes, they do believe she plagiarized the speech. weigh in for yourself. for tonight headline speakers we'll hear from two of donald trump's children. tiffany and donald jr. new jersey governor chris christie is speaking as house speaker paul ryan. maureen: joining us live from cleveland is chief political correspondent scott thuman. scott, talk about the delegate roll call i understand is about to begin. are we going to hear from anything from the dissident delegates? scott: that is the question everyone is asking tonight. no one seems to be exactly

rebillion like the one we saw last night. they will make sure the delegate chair will stand up and say we stand in favor of -- they will say presumably donald trump. however, you don't know after seeing last night's display. there is a chance there will be angry voices or people from the stop trump movement who may try to have their opinion heard. we are all on standby to see what happens there. in the meantime, one of the other conversations you were talking about was the speech melania trump's speech last night that has become so controversial. i talked with quite a few people who had their speeches dissected over the years. former presidential candidates mike huckabee and rick perry today. both of them saying much to do about nothing. they are republicans. they are here on point. so they are trying to be dismissive of
