after a transportation hub. train station next door. they shut down the transportation. surrounded the mall. there is a huge presence there from the police. what they are not sure at this point is a lone gunman or are there multiple gunmen? they did not get accurate reporting from people there so it's confusing. so with that said, they are searching for other potential suspects in this case. other gunmen. we know one body found at the location had a gun next to it and they believe it was one if not the only gunman who took his own life after opening fire. the scene at the hospital they have been taking the victims, some heartbreaking. there were small children inside the mcdonald's. he started there and walked out and then walked back in and started going toward the mall. a very busy mall this time of day. as soon as we get more information about what is happening there, specific information. right now again as i said

look at hillary clinton in tampa, florida. she is offering a blistering critique in the last 15 or 20 minutes of donald trump and his speech last night at the republican national convention. now to tim kaine. he was in boston today for a democratic fundraiser and slated for another one today in rhode island. camera crews catching up with the virginia senator. he had no comment on the v.p. search. hillary clinton before the rally in tampa as maureen mentioned holding a round table discussion in orlando with victims, family members and the first responders of the pulse nightclub shooting. last week you may remember clinton and tim kaine appeared together in annandale. they had a good rapport. laughing and smiles. tim kaine who is fluent in spanish could help hillary clinton with latino voters nationwide. another big aspect is the popular standing in the key swing state of virginia. >> you talk about somebody who has won statewide elections in a given state. they hav

over the place. these are democratic activists who work to elect hillary clinton, they work that much harder if there is a virginian on the ticket. jeff: that could be another reason that tim kaine as we have been hearing number one on her list. i have been in contact with people in the kaine campaign throughout the day. they have not received any information from the clinton campaign. so it seems as though at the moment they are waiting just like the rest of us. we do expect an announcement at some point today from hillary clinton on who her v.p. pick will be. it's remarkable it has not leaked. everybody watching closely as we wait for the big announcement. back to you, maureen and leon. maureen: thank you. donald trump followed up his marathon speech from last night's republican convention by rekindling his publish feud with senator ted cruz. while addressing supporters in cleveland, trump spent 15 minutes blast his formal rival and he said he discuss not want cruz's endorsement -- he does not want cruz's endorsement.

high school. still 88 degrees there. muggy. through the day, some period of the cloudiness. when the sun was bright the temperature soared. we got late afternoon cloudiness to knock temperatures down. that is a good deal. i don't think we get that break for the next couple of days. we'll have more sunshine and higher temperatures. officially at washington today, reagan national. 95 was the high. six degrees above average. nowhere near the record high in 103. i don't think we will see the record high air temperatures the next four or five days. but the combination of the temperature and the humidity in the air will make it feel like 103 or higher over the next few days. in order to get a heat advisory we need 105 feels like temperatures or heat index for three hours or more. that could happen. but we are not quite there as i said. it feels like 100 in leesburg and feels like 98 in annapolis and washington. through the evening, it will be warm and muggy. air temperatures at 3:00 in the morning still going to be 80 degrees. the heat index or the feels-like temperates

middle 80's. so when you get up tomorrow morning or early in the morning it's already hot and humid and will become more so throughout the day. if we are look for a chance of cooling storms, keep looking. it's not going to happen around here tonight. maybe tomorrow afternoon. check out the heat index on the computer. suggestions that it could be 106 tomorrow afternoon. 101 in leesburg. 103 in manassas.he midshore and easton. 107 in fredericksburg. again if we have numbers like that expected over three-hour period there will be a heat advisory. on sunday we get a bit of a break. look like the winds or drier air may come up away from the north. may knock the feels like to 100 degrees. the more excessive heat from the south comes back on us for monday. final day of the citi open, tough stuff. the air temperatures near 100 degrees. i will feel warmer and it will be muggy and light winds. tough weather. as we have been telling you. if it's not at the park

tennis channel as well. all right, the next seven days. no real relief. upper 90's to near 100 through monday. mid-90's tuesday, wednesday, thursday. lower 90's by friday. best chance of storms are monday, tuesday, wednesday. maureen: thank you, doug. we have a new way for you to send us your picture and videos. go to burst.com/wjla. it's an easy way to get us the news and the weather that you see during your day. leon: let's see what scott abraham is seeing at the citi open this evening. hey, scott. scott: hey, guys. i will tell you what. i'm jealous of the air conditioning in the studio. i need an air conditioning units here. one of the portable ones. you know why it's good? we had fantastic tennis action at the citi open. john isner going toe to toe whatcha' doin? just checking my free credit score at credit karma.
