Even though many agents' cell phones had their contents curiously erased, the Secret Service has turned over more than one million documents from agents involved in the protection details of the President and Vice President from before and on the day of the January 6th Republican-led domestic terrorist attack on Congress.
According to NBC News, the communications include things like emails, radio transmissions, Microsoft Teams chat logs and other methods that can help detail the planning for the day. Questions about the Secret Service's operations arose when agents tried to remove Vice President Mike Pence from the Capitol, and Donald Trump reportedly tussled with Secret Service agents to drive him to the Capitol to lead the assault; the agents returned him to the White House.
Secret Service communications have also come into question because Oath Keeper founder Stewart Rhodes reportedly told members of his group that he had direct contact with at least one member of the Secret Service, saying he had a direct line to Trump. Rhodes and four other Oath Keeper leaders are currently on trial for seditious conspiracy and other charges.
