The words of Donald Trump supporters who are accused of participating in the deadly U.S. Capitol riot may end up being used against him in his Senate impeachment trial as he faces the charge of inciting a violent insurrection.

At least five supporters facing federal charges have suggested they were taking orders from the then-president when they marched on Capitol Hill on Jan. 6 to challenge the certification of Joe Biden’s election win. But now those comments, captured in interviews with reporters and federal agents, are likely to take center stage as Democrats lay out their case. It’s the first time a former president will face such charges after leaving office.

“I feel like I was basically following my president. I was following what we were called to do. He asked us to fly there. He asked us to be there,” Jenna Ryan, a Texas real estate agent who posted a photo on Twitter of herself flashing a peace sign next to a broken Capitol window, told a Dallas-Fort Worth TV station.

Trump is the first president to be twice impeached and the first to face a trial after leaving office. The charge this time is “inciting violence against the government of the United States.” His impeachment lawyer, Butch Bowers, did not respond to call for comment.
