Homeland Security Secretary Announces Panel on Trump Assassination Attempt

The homeland security secretary, Alejandro N. Mayorkas, on Sunday announced the members of a panel to conduct an independent review into security failures after a gunman was able to wound former President Donald J. Trump last weekend at a campaign rally in Butler, Pa.

The Secret Service, which answers to Mr. Mayorkas, is facing criticism for its decisions in planning security for the event, and Republican leaders have called for the agency’s director, Kimberly A. Cheatle, to resign. Mr. Mayorkas’s announcement on Sunday promised that the panel would get to the bottom of what went wrong and what changes the Secret Service should make to protect the country’s leaders.

“This independent review will examine what happened and provide actionable recommendations to ensure they carry out their no-fail mission most effectively and to prevent something like this from ever happening again,” Mr. Mayorkas said in a statement.

The panel — described by Mr. Mayorkas as bipartisan — that will be conducting the 45-day review will be made up of Janet Napolitano, a former homeland security secretary; Frances Townsend, a former homeland security adviser to President George W. Bush; Mark Filip, a former federal judge and a deputy attorney general under Mr. Bush; and David Mitchell, a former secretary of the Delaware Department of Public Safety and Homeland Security. Mr. Mayorkas said he could invite additional experts to join the panel in the coming days.

Ms. Cheatle said in a statement on Sunday that she was eager to cooperate with the review.

The announcement comes as Mr. Mayorkas is under scrutiny for his handling of the events surrounding the assassination attempt, especially whether he has been able to get adequate answers from Ms. Cheatle.
