RNC Day 1: Here's what to expect as the RNC kicks off in Milwaukee after Trump assassination attempt

Washington – The Republican National Convention kicks off Monday in Milwaukee, Wisconsin, where the GOP is set to formalize the nomination of former President Donald Trump just days after an assassination attempt against the former president. 

Republicans from across the country are descending on Milwaukee's Fiserv Forum arena to nominate Trump, who clinched the nomination in March having amassed the 1,125 delegates needed. 

How the shooting reshapes the convention remains to be seen. Secret Security officials said Sunday that the agency has been working on the RNC security plan for more than a year, and the plan will remain in place.
