A former White House aide may have delivered the kind of political blow to former U.S. President Donald Trump that his would-be rivals for the Oval Office in 2024 have yet to land.

Cassidy Hutchinson’s testimony to the House Jan. 6 committee Tuesday presented startling glimpses of uncontrolled rage sure to sear into the public consciousness, even as a portion of her testimony has been thrown into question.

The vivid portrayal was laid out for the American public just as Trump is considering another run for the presidency in 2024, and as potential rivals are stepping up to try to loosen his grip on Republican voters. Former Trump chief of staff Mick Mulvaney tweeted afterward that it was "A very, very bad day for Trump.”
