 Today we begin with what we know about the shooting and the security failures that led to yesterday's events. President Trump is headed to the Republican National Convention, which begins today in Milwaukee. Laura Davison, news and politics editor at Bloomberg, joins us live now from the RNC. Laura, welcome to the show. Thanks for having me. Also with us from D.C. is Gabe Fleischer. He's the author of the Wake Up to Politics newsletter. Gabe, it's great to have you back.
