 We knew investigators also had found explosive devices in Crook's car. I'm now told that the two devices in that car that were found had radio controls to detonate them remotely, and that investigators found a transmitter on Crook's body on the roof where he was killed. Okay, now that one piece of this investigation is obviously what we've talked about, the shooter. The other big piece is how a shooter was able to get in a position with an actual sight line on Trump.
