Cassidy Hutchinson is expected to testify before the Jan. 6 committee Tuesday. As an aide to Trump's chief of staff Mark Meadows, she had a key vantage point and has already dished to the committee about her former boss. She has told the committee about White House strategy sessions where Republican House members, whom she named, discussed how to reject electors from certain states Joe Biden won in the 2020 election. The committee on Monday called the unexpected hearing to present "recently obtained evidence and receive witness testimony," according to the announcement. The committee had signaled last week that it wouldn't hold another hearing until July. For more on this surprise witness and her expected testimony, visit the link in bio.
