 We're live from the site of the Republican National Convention here in Milwaukee, Wisconsin. Several Republican members of Congress were in the front row of Trump's rally last night in Pennsylvania. Let's talk to one of them now, Congressman Dan Muser from eastern Pennsylvania. Congressman, thank you so much, and we're so glad you're okay. You were in the front row of this rally when the gunfire broke out. What can you tell us about what you saw, and what is your general reaction now that you've had a little time to process it?
