The Department of Homeland Security — Secret Service’s parent agency — is subject to oversight of the DHS Office of Inspector General, which had requested records of electronic communications from the Secret Service between January 5 and 6 of 2021, before being informed that they had been erased. It is unclear from the letter whether all of the messages were deleted, or just some. DHS officials have also pushed back on the OIG’s records request by arguing that the records must first undergo review by DHS attorneys, which has delayed the process and left unclear if the Secret Service records would ever be produced, according to the letter.

Asked about the matter, a DHS-OIG spokesperson told The Intercept, “To preserve the integrity of our work and protect our independence, we do not discuss our ongoing reviews or our communications with Congress.”

A top Secret Service official allegedly involved in the attempt to spirit away Pence on January 6 remains in a leadership position at the agency. Tony Ornato, a Secret Service agent whom Trump made the unprecedented decision to appoint as his deputy White House Chief of Staff, reportedly informed Pence’s national security advisor, Keith Kellogg, on January 6 that agents would relocate the Vice President to Joint Base Andrews. “You can’t do that, Tony,” Kellogg reportedly told Ornato. “Leave him where he’s at. He’s got a job to do. I know you guys too well. You’ll fly him to Alaska if you have a chance. Don’t do it.” (Ornato has denied the account.)
