Rep. Steve Scalise, R-La., has called for answers from the Secret Service following the attempted assassination of Donald Trump at a rally in Butler, Pennsylvania.

Scalise, chairman of the House Oversight Committee, subpoenaed Secret Service Director Kimberly Cheatle to testify Monday before the committee in a hearing on the circumstances surrounding the shooting.

In a statement, Anthony Guglielmi, chief of communications for the Secret Service, confirmed that Cheatle will attend the hearing.

"The Secret Service is fully accountable for the safety of its protectees. We are committed to better understanding what happened before, during, and after the assassination attempt of former President Trump to ensure it never happens again. That includes cooperation with Congress, the FBI and other relevant investigations," Guglielmi said.

In the wake of the shooting, Republicans and some Democrats immediately raised questions about the performance of the agency, including about how a gunman was able to get so close to the former president and fire multiple shots.

In his letter to Cheatle, Chairman James Comer, R-Ky., accused the Secret Service of a lack of transparency in issuing the subpoena.

"Americans demand answers from Director Kimberly Cheatle about the Secret Service’s historic security failures that led to the attempted assassination of President Trump, murder of an innocent victim, and harm to others in the crowd. We look forward to Director Cheatle’s testimony on Monday, July 22 to deliver the transparency and accountability that Americans deserve," Comer said in response to Cheatle confirming she would testify.

In addition to the Oversight Committee hearing, the House Homeland Security committee has called for a hearing and has subpoenaed documents from DHS Secretary Alejandro Mayorkas. In the Senate, both Homeland Security Committee Chairman Gary Peters, D-Mich., and ranking member Rand Paul, R-Ky., have launched an investigation.

The DHS Office of Inspector General is also reviewing the Secret Service’s handling of the rally.

In a preview of the pressure Cheatle may face, she was confronted by multiple Republican senators at the Republican National Convention on Wednesday.

"This was an assassination attempt, you owe the people answers, you owe President Trump answers," Sen. Marsha Blackburn, R-Tenn., said.

Cheatle, meanwhile, has called the shooting "unacceptable" and "something that shouldn’t happen again."

"The buck stops with me," she told ABC News last week. "I am the director of the Secret Service, and I need to make sure that we are performing a review and that we are giving resources to our personnel as necessary."

However, in response to the intense criticism from lawmakers, the Secret Service says she does not intend to resign.

"Continuity of operations is paramount during a critical incident and U.S. Secret Service Director Kimberly Cheatle has no intentions to step down," Guglielmi said. "She deeply respects members of Congress and is fiercely committed to transparency in leading the Secret Service through the internal investigation and strengthening the agency through lessons learned in these important internal and external reviews."
