The brief was a key witness to the tumultuous final days of the Trump administration as Donald Trump tried to hang on to power, pressuring those around him to find ways to overturn the outcome of the 2020 presidential election. Short was in the Oval Office on January 4, 2021, when Trump lawyer John Eastman tried to convince Pence to delay certifying the Electoral College vote. The plan involved the vice president making false claims that there were problems with electoral votes that were certified for the winner of the 2020 race, Joe Biden. (Pence refused to go along with the plan.)

In several investigations, prosecutors have worked on schemes to create a false slate of voters who would have voted for Trump instead. Eastman and other lawyers involved in the project, including Rudy Giuliani and the Justice Department’s Jeffrey Clark, have also been investigated.

On January 6, Short was at the Capitol with Pence as the vice president had to flee from pro-Trump rioters who stormed the building, some chanting, “Hang Mike Pence.”

Short has already cooperated with the House Select Committee that is also investigating the events surrounding the January 6 attack.

The Justice Department investigation has been largely under wraps compared to the House inquiry and its public hearings, but the agency in March said it had expanded its criminal investigation. Incorporating preparations for a pre-coup rally into the January 6 attack.

Other grand jury subpoenas have been issued to people who helped organize and plan the rally. Attorney General Merrick Garland said last week that the Justice Department will do “Hold accountable anyone who is criminally responsible for attempting to overturn a legitimate election, and we must do so in a manner full of integrity and professionalism.”
