 The shooting occurred as Trump supporters are gearing up for tomorrow's start of the Republican National Convention in Milwaukee. Chief U.S. analyst for AGF Securities, Greg Vallier, says security will be even tighter than it already was following the attack against the former president. I think everyone, first and foremost, is grateful that he's alive. This shooter missed him by inches. So I think everyone's taking a deep breath and being thankful that he is alive. Next will come an intense focus on security.
