10 hearings, 1,000 interviews, millions of documents: the House panel has spoken

Whodunnit? He did it.

Yet take a step back and consider how it will look to future historians. A former president of the United States stands accused by Congress of obstructing an official proceeding, conspiring to defraud the United States, conspiring to make a false statement and inciting, assisting or aiding or comforting an insurrection.

Just as before, congressional aides, journalists and members of the public gathered in a caucus room measuring 74ft long by 54ft feet wide with six windows, two crystal chandeliers hanging from a double-height ceiling decorated with classical motifs. It once was the site of some of the most publicised hearings of the House Un-American Activities Committee in the 1950s.

There was also some new evidence, including a recent interview with longtime Trump aide Hope Hicks.

When he spoke forcefully on Monday, outlining the referrals of Trump to the justice department on criminal charges, the atmosphere in the room shifted to a more sombre one. The referrals are mostly symbolic with the department ultimately deciding whether to prosecute Trump or others.

But they provide another wake-up call for the Republican party. Since the last January 6 hearing, Trump has announced that he is running for the White House again while his handpicked election-denying candidates have been routed in the midterm elections. The ghosts of elections past, present and future are converging. There has seldom been a better opportunity for Republicans to disown him.

The committee, which will dissolve on 3 January with the new Republican-controlled House, voted to approve its final report, expected later this week. Thompson brought down the gavel and people in the public gallery broke into polite but heartfelt applause. After a year and a half wading through obstruction, hype and scepticism, the chairman and his team delivered the goods.
