 There was apparently a desperate attempt to stop the shooter before he got those shots off. But the critical question is how that shooter was able to get on the roof in the first place unimpeded. The members of Congress are calling on the Secret Service director to appear before Congress on July 22nd. They have to be more transparent than they've been. The president is also calling for an independent investigation into what took place on that Pennsylvania field. So that'd be a week from today.
