The House of Representatives is launching a task force to investigate this month’s attempted assassination of former President Donald Trump, announced Speaker Mike Johnson, R-La., and Minority Leader Hakeem Jeffries, D-N.Y., on Tuesday.

A vote on Wednesday evening to establish the task force passed the House unanimously in a 416-0 vote.

The panel will be made up of seven Republicans and six Democrats and will have subpoena authority.

On July 13, a 20-year-old man perched on a nearby warehouse rooftop fired several shots at Trump during a campaign rally in Butler, Pennsylvania, striking the former president in the right ear. One rallygoer was killed, and two others were wounded. The gunman was fatally shot by a Secret Service sniper.

Johnson said during a news conference Tuesday morning the assassination attempt “necessitates a specific, precise and quick action by the Congress.”

“While we have a number of committees of jurisdiction who have already done great work on this … I think the moment calls for something unique and different,” he said. 

Johnson said the committee will include members of Congress who have expertise in different areas related to the investigation. He said a list of task force members will be released by the end of the week.

The panel will have three primary responsibilities, the speaker said.

“We have to get the answers, of course, about what happened,” Johnson said. “We need to make sure that accountability is ensured to the American people, and that we need to prevent anything like this from ever happening again.”

The task force will begin immediately and issue a final report by Dec. 13, Johnson said. He added that “we could probably expect” some interim reports as well.

“We have a finite set of facts and circumstances here with regard to the event … but there are deeper problems, obviously, in the Secret Service,” Johnson said. “And I think this task force would be the way for us to get to the bottom of that.”

In a House Oversight Committee hearing Monday, members of both parties called for Secret Service Director Kimberly Cheatle to resign. 

After resisting such calls for the past week, Cheatle stepped down Tuesday morning.

"Today, you failed to provide answers to basic questions regarding that stunning operational failure and to reassure the American people that the Secret Service has learned its lessons and begun to correct its systemic blunders and failures," committee Chairman James Comer, R-Ky., and ranking member Jamie Raskin, D-Md., said in a statement following Monday’s hearing. 

"In the middle of a presidential election, the Committee and the American people demand serious institutional accountability and transparency that you are not providing," they continued. "We call on you to resign as Director as a first step to allowing new leadership to swiftly address this crisis and rebuild the trust of a truly concerned Congress and the American people."

House Republicans had been preparing a resolution urging President Joe Biden to fire Cheatle.
