The House select committee investigating the Jan. 6, 2021, attack on the U.S. Capitol issued a subpoena to the U.S. Secret Service on Friday requesting records after a government watchdog accused the agency of erasing texts from Jan. 5 and 6 after his office requested them. …

The subpoena is the first the committee has issued to an executive branch agency.

The text messages could provide insight into the actions of the agency and potentially those of President Donald Trump on the day of the insurrection. Former White House aide Cassidy Hutchinson testified during a hearing last month that Trump wanted to lead the mob from the Ellipse to the Capitol, despite knowing they were armed, and said that she was told by an agent that Trump physically assailed the Secret Service agent who informed him he could not go to the Capitol.

Secret Service spokesman Anthony Guglielmi said Thursday that the agency did not maliciously delete text messages following the request from DHS’s Office of Inspector General. The Washington Post previously reported that the Secret Service began a preplanned, agency wide replacement of staff telephones a month before the Office of Inspector General’s request, according to two people briefed on the document request.
