CNN —US Secret Service Director Kimberly Cheatle said Monday “the buck stops with me” as questions have swirled about the agency’s security preparations following the assassination attempt on former President Donald Trump Saturday. Cheatle told ABC News on Monday that “the Secret Service is responsible for the protection of the former president” and “the buck stops with me, I am the director of the Secret Service.” She says she plans to stay on as director. “The Secret Service is tasked with the tremendous responsibility of protecting the current and former leaders of our democracy,” Cheatle said. “It is a responsibility that I take incredibly seriously, and I am committed to fulfilling that mission.”House Oversight Committee Republicans sent a letter to Cheatle with a new series of document requests and a notice to preserve all documents and communications regarding Trump’s Butler, Pennsylvania, rally, as the committee separately investigates the assassination attempt. CNN’s Annie Grayer and Whitney Wild contributed to this report.
