More witnesses are coming forward with new details on the Jan. 6 U.S. Capitol riot following former White House aide Cassidy Hutchinson’s devastating testimony last week against former President Donald Trump, says a member of a House committee investigating the insurrection.

The panel already has subpoenaed former White House counsel Pat Cipollone, who investigators remain hopeful will appear Wednesday for a deposition, and said it would also welcome follow-up details from Secret Service members with Trump that day.

Rep. Adam Kinzinger, R-Ill., cited Hutchinson’s testimony that Trump wanted to join an angry mob of his supporters who marched on Jan. 6, 2021, to the Capitol, where they rioted, as particularly valuable in “inspiring” more people to step forward as the committee gets set for at least two public hearings this month.

“Every day we get new people that come forward and say, ‘Hey, I didn’t think maybe this piece of the story that I knew was important,’” he said Sunday. “There will be way more information and stay tuned.”
