Trump assassination attempt at rally; Milwaukee RNC; Biden Oval Office address: Live updates

Pesident Joe Biden gave an Oval Office address Sunday — a rare form of presidential remarks reserved for the most solemn times — and urged Americans to unite and take the temperature down on politics following an assassination attempt on former President Donald Trump during a campaign rally in Pennsylvania.

Here’s what else to know:

Biden’s speech: The president condemned political violence and said “disagreement is inevitable and American democracy is part of human nature, but politics must never be a literal battlefield or, God forbid, a killing field.” He warned against the normalization of this violence and urged Americans to step out of their political silos “where we only listen to those with whom we agree, and where disinformation is rampant, where foreign actors fan the flames of our division to shape the outcomes consistent with their interests, not ours.”

Trump’s movements: The former president said on Truth Social that he is going to Milwaukee, Wisconsin, on Sunday for the Republican National Convention after initially considering delaying his trip. After the assassination attempt at the rally in Butler, Pennsylvania, on Saturday, Trump flew to Newark, New Jersey, and spent time with his daughter Ivanka at his golf club in Bedminster, sources told CNN. The Secret Service said Sunday that there are no plans to tighten security plans for the RNC, saying it is confident in the plans that are in place.

What happened at the rally on Saturday: Trump’s rally speech in Butler, Pennsylvania, Saturday evening began just as it had at dozens of rallies previously – his attendees chanted “USA! USA!” and the former president clapped and pointed to faces in the crowd before taking the lectern. About 150 yards to the north, a gunman was climbing onto the roof of a building outside the rally security perimeter. He had an AR-style weapon with him. Six minutes into the former president’s speech, the gunman took aim at Trump and squeezed the trigger. Here’s a timeline.

Gunman was spotted: A local police officer saw the gunman on a rooftop during campaign rally but was unable to engage him, Butler County Sheriff Michael Slupe told CNN on Sunday. Slupe said that Butler Township officers received calls about a suspicious person outside the perimeter of the rally and went looking to find that person. He said the initial calls that came in did not indicate the suspicious person had a gun. 

New investigation details: The shooter, 20-year-old Thomas Matthew Crooks, had no prior contacts with the FBI and had not been previously on its radar or databases. Investigators are struggling to understand his motives. Crooks used an AR-style 556 rifle purchased legally by his father, FBI officials said, and one of the things that investigators are still looking to understand is how Crooks gained access to his father’s firearm. He also had “rudimentary” explosive devices in his car, an official said.

About the shooter: A former classmate and co-worker told CNN they remember Crooks as “the sweetest guy.” The colleague said Crooks was “not a radical” and never expressed any political views at work. “It’s hard seeing everything that’s going on online because he was a really, really good person that did a really bad thing. And I just wish I knew why,” the colleague said.  

Congress: House Speaker Mike Johnson on Sunday called for the country “to get back to civility” and said he hasn’t gotten a “satisfactory answer” yet from US Secret Service on the “security lapse” at Trump’s Pennsylvania rally.
