One spectator was killed and two were hurt in the shooting on July 13.
Federal authorities are investigating after former President Donald Trump was shot in the ear in an assassination attempt at an election rally in Butler, Pennsylvania, on July 13.
The alleged shooter was killed by snipers. One spectator was killed and two were hurt, officials said.
Former President Donald Trump will hold his first rally since the assassination attempt this Saturday, July 20, at an arena in Grand Rapids, Michigan, his campaign said.
Trump’s vice presidential pick, Sen. J.D. Vance, will also appear at the rally.
House Homeland Security Committee Chairman Mark Green, R-Texas, is calling on Secret Service Director Kim Cheatle, Secretary of Homeland Security Alejandro Mayorkas and FBI Director Christopher Wray to testify before the committee on Tuesday, July 23.
"The American people want answers," Green said in a statement. "It is imperative that we partner to understand what went wrong, and how Congress can work with the departments and agencies to ensure this never happens again."
Cheatle is expected to testify before the GOP-led House Oversight Committee on Monday, July 22.
One of the men injured in Saturday's shooting, 57-year-old David Dutch, was shot in the chest and liver, according to the Marine Corps League of Pennsylvania.
Dutch is no longer in a medically induced coma and has been upgraded from critical to stable condition, the organization said.
Dutch is a former Marine who serves as commandant of his Marine Corps League detachment, the organization said.
The other injured victim, 74-year-old James Copenhaver, has also been upgraded from critical to stable condition, officials said.

In a private phone call with Robert F. Kennedy Jr., former President Donald Trump said the bullet "sounded like the world’s largest mosquito."
RFK Jr.'s son posted on X a video of the call, which was filmed from what looks to be RFK Jr.'s hotel room. RFK Jr. had Trump on speaker phone.
The younger Kennedy, Bobby Kennedy III, removed the post after his father said on X that he was "mortified" it became public.
Trump also told RFK Jr. about the phone call he received from President Joe Biden after Saturday’s assassination attempt.
"It was very nice, actually. He called me, and he said, 'How did you choose to move to the right?' [Inaudible] Everybody’s looking straight on," Trump said. "I said, 'I was just showing a chart.'"
