But additional corroboration of Hutchinson's account has emerged since her testimony. CNN reported earlier this month that two Secret Service sources have said they heard about Trump angrily demanding to go to the Capitol and berating his detail when he didn't get his way.

The sources told CNN that stories had circulated about the incident following January 6, which included details similar to what Hutchinson described.

In addition, CNN reported on Thursday that a Metropolitan Police Department officer corroborated details of Hutchinson's account and recounted what was seen to committee investigators.

This story has been updated with additional developments Saturday.

CNN's Zachary Cohen, Ryan Nobles, Annie Grayer, Jamie Gangel and Whitney Wild contributed to this report.
