Everything we know about the attempted assassination of former President Trump

The latest: The Department of Homeland Security's inspector general said Wednesday it opened an investigation into the Secret Service's handling of security at the event.

• The FBI said it's examining "suspicious devices" found in searches of a vehicle and the Bethel Park, Pennsylvania, home of suspect Thomas Matthew Crooks that were "rendered safe by bomb technicians."
• The motives of the 20-year-old suspect, who died during the shooting, remain unclear in the aftermath of the attack that's raised concerns about a fractured nation plagued by growing threats against elected officials.

What happened

Sounds of gunshots rang out a little over six minutes into Trump's Saturday evening remarks. Screams erupted as the presumptive Republican presidential nominee ducked for cover.

• As wounded victims and fearful supporters lay on the ground, the former president rose surrounded by Secret Service agents, his face bloodied and his fist lifted in defiance.
• In a Saturday Truth Social post, the former president recalled hearing "a whizzing sound, shots, and immediately felt the bullet ripping through the skin."
• The shooter "fired multiple shots toward the stage from an elevated position outside of the rally venue," Secret Service spokesman Anthony Guglielmi said.
• A Secret Service sniper returned fire and killed the shooter who was less than 450 feet away from Trump, satellite imagery indicates.

What we know about those shot

Corey Comperatore, 50, from Sarver, Pennsylvania, was confirmed to have died during the attack.

• The former Buffalo Township Volunteer Fire Company chief was killed as he dived to protect his family members during the attack, authorities said.
• The conditions of the two Pennsylvanian men critically injured in the shooting, 57-year-old U.S. Marine veteran David Dutch, of New Kensington, and 74-year-old James Copenhaver, from Moon Township, were listed as stable as of late Sunday.

A bullet grazed Trump's ear during the shooting, but his campaign said he was "fine" after being checked at a local medical facility.

What we know about the shooting suspect

Crooks, a 20-year-old from the Pittsburgh suburb Bethel Park, Pennsylvania, reportedly graduated from Bethel Park High School in 2022 and was a recipient of an honor award, local media previously reported.

• An individual matching Crooks' name is registered as a Republican in Allegheny County, Pennsylvania, and campaign finance data shows a $15 donation was made to a political action committee that aims to mobilize Democratic voters.
• Authorities believe at this stage of the investigation that the suspect was "a lone actor."

Biden, on RNC eve: Politics must never be "a killing field"

President Biden said Sunday he has directed an independent national security review to investigate the shooting.

• The president built on comments he made earlier denouncing the assassination attempt in an address to the nation on Sunday night in which he spoke of the need to "lower the temperature" in U.S. politics.

• "Disagreement is inevitable in American democracy. It's part of human nature," he said. "But politics must never be a literal battlefield. God forbid a killing field."

Top Republicans and Democrats united in denouncing violence

Congress members, cabinet officials and former presidents have condemned the shooting.

House Majority Leader Steve Scalise (R-La.), who was critically injured in the 2017 congressional baseball shooting, is calling for the nation to focus on policies and not the "demonization of Donald Trump."

Senate Majority Leader Chuck Schumer (D-N.Y.) said in a statement that he's "horrified by what happened at the Trump rally in Pennsylvania and relieved that former President Trump is safe."

House Speaker Mike Johnson (R-La.) said in a post on X: "This horrific act of political violence at a peaceful campaign rally has no place in this country."

Vice President Kamala Harris said in a statement: "We must all condemn this abhorrent act."

Congress launches multiple investigations

In addition to the FBI probe and the security review ordered by Biden, several House and Senate committees have moved to investigate, as well.

• The House Committee on Oversight and Accountability will hold the first congressional hearing on the shooting on July 22 with Kimberly Cheatle, director of the Secret Service.
• The Senate Homeland Security and Government Affairs Committee has also requested a briefing from the Secret Service, the Department of Homeland Security and the FBI.
