The California Democrat, though, would not say whether she believed that a financial crime had been committed.
“I’m not saying it’s a crime, but I think it’s a grift,” Lofgren continued.
CNN has reached out to Guilfoyle for comment. Turning Point also declined to comment.
In addition to her role on the campaign and during the rally, Guilfoyle helped raise money for rally organizers leading up to the event.
The committee had subpoenaed Guilfoyle for testimony after she abruptly ended an interview with investigators in February. Guilfoyle had agreed to be interviewed voluntarily in February, but became upset when her appearance was reported in the media and when she learned that members of the committee were allowed to participate in the interview — which is a routine occurrence in congressional inquiries.
Lofgren told Tapper on Monday that the panel’s presentation is “not the end of it.”
“We interviewed more than 1,000 people. We’ve got hundreds of thousands of documents, and obviously you can’t present everything in a two-hour hearing, so this is not the end of it… but we’ll have detailed information as time goes on,” she said.
The House committee is holding a series of hearings this month that are designed to show Trump was at the center of a conspiracy to prevent the certification of the 2020 presidential election results and the peaceful transfer of power. It has held two public hearings so far in June, featuring never-before-seen video and testimony.
This story has been updated with additional developments Tuesday.
CORRECTION: This story has been updated to correct the name of the organization that paid Guilfoyle for her January 6, 2021 speech.
