 Good morning, I'm Michelle Bash. And I'm John Aaron. Coming up, you can expect record numbers of people at the airport this 4th of July. I'm Neil Orkenstein. One heat wave you can handle, but what happens to your body when they become routine? I'm John Doman. More problems with D.C.'s troubled 911 center. This is literally life and death. I'm Lynn Bowie. Fixing the process used to screen renters after allegations of discrimination. I'm Scott Gelman. It's 8 o'clock.
