Chris Hayes joined the calls for President Donald Trump to be impeached over his role in inciting the violent insurrection at the U.S. Capitol on Wednesday, speaking on the topic at length in the opening monologue of Thursday’s episode of All In With Chris Hayes. Hayes opened his remarks noting that the House of Representatives was considering impeaching Trump for a second time, something that has never happened before in American history. Hayes read a letter from House Judiciary Chairman Jerry Nadler (D-NY), who had presided over Trump’s impeachment a year ago and is saying that it needs to happen again.
