Some of the most intriguing moments in the impeachment fight on Capitol Hill take place in private, away from the hearing rooms and news conferences that throngs of cameras can scrupulously document.

Democratic and Republican representatives alike granted The New York Times unusual access to photograph their preparations for the Judiciary Committee hearing this week and the drafting of articles of impeachment.

The photos yield a rare behind-the-scenes look at how Congress really operates — long days fueled by adrenaline, a sense of history and takeout food — and the interludes of quiet from the impeachment pressure cooker.
