Why today's 1/6 hearing was utterly devastating for Donald Trump

To date, the January 6 committee has provided a clinical, step by step breakdown of who knew what when in the days leading up to the insurrection at the US Capitol.

The committee's hearing on Tuesday was something quite different -- as Cassidy Hutchinson, a former top aide to Trump White House chief of staff Mark Meadows, provided stirring and intimate details of what happened that day and, specifically, how Donald Trump acted.

It was, in a word, ugly.

Three moments stand out:

1) Hutchinson said she was told that when Trump got back into the presidential limousine, known as the Beast, and was told that he could not join protesters at the Capitol, he lost it. The then-President tried to grab the steering wheel and, when one of his security detail reached to stop him, he grabbed at that man's throat.

2) Trump, in expletive-laden language, urged that people with weapons -- guns, knives and the like -- be let through the magnetometers before his speech to the "Stop the Steal" rally. His goal? Ensure that the photographs and video of the event showed a packed crowd all listening to him. "They're not here to hurt me," Trump reportedly told people.
