The U.S. Secret Service (USSS) is facing several investigations surrounding the assassination attempt against Donald Trump.

The Department of Homeland Security’s (DHS) inspector general has launched an investigation into the Secret Service following the assassination attempt on Donald Trump.

According to a notice posted on the Inspector General’s website, the objective of the investigation is to “evaluate the United States Secret Service’s (Secret Service) process for securing former President Trump’s July 13, 2024 campaign event.”

The investigation’s start date was not listed.

Probes into the Secret Service are also being conducted by members of Congress.

The House Oversight Committee called Secret Service Director Kimberly Cheatle to testify on July 22.

The letter said the Committee has “initiated an investigation into today’s assassination attempt on President Trump and requests your voluntary appearance at a full Committee hearing on July 22, 2024.”

Representative Mark Green (R-TN), Chairman of the House Committee on Homeland Security, also sent letters to Department of Homeland Security (DHS) Secretary Alejandro Mayorkas, Federal Bureau of Investigation (FBI) Director Christopher Wray, and Secret Service (USSS) Director Kimberly Cheatle, calling them to testify on July 23.

“The American people want answers on what happened Saturday in Pennsylvania. Secretary Mayorkas and Director Cheatle are responsible for the department and the agency charged with securing our homeland and protecting our nation’s chief executives and candidates, while Director Wray leads the agency with the vital responsibility of investigating this attempted assassination,” Green said in a statement.

The Senate Committee on the Judiciary’s Republicans issued a call for Senator Dick Durbin (D-IL), Chairman of the committee, to hold a hearing over matters pertaining to the USSS.

“There is much unknown about this attempted assassination, but its occurrence raises alarming questions and concerns,” the Republicans wrote, adding, “The Senate Committee on the Judiciary has an obligation to exercise its jurisdiction and oversight authority over the United States Secret Service, the Department of Homeland Security, and the Federal Bureau of Investigation to shed light on this grave matter.”

Ranking Member and Chairman of the Senate Homeland Security and Governmental Affairs Committee, Senators Rand Paul (R-KY) and Gary Peters (D-MI), have also announced that the committee will direct a bipartisan investigation into the USSS.

“This committee has an obligation to unearth the truth about the failures on Saturday and before, no matter how inconvenient to the government. We will leave no stone unturned,” Paul said in a statement.
