No need to read between the lines with Berman's statement

[Tom Rinaldo]

15. In the stretch run to the end of Trump's term more of those who honor their oath of office

are stepping out of the shadows to resist the undermining of the U.S. Constitution, including those who held significant offices in recent years and increasingly those still holding some. Increasing profiles in responsibility and in some cases courage are emerging in the Judicial branch of government. Top military leaders, both past and present, who normally are loathe to challenge an elected Commander in Chief, have started to draw the line with Trump. More whistle blowers are emerging from inside his administration despite how Trump savages them. Even mainstream media is growing less reluctant to speak openly of both Trump's lies and authoritarian tendencies. I think everyone senses that now is the time for the showdown, the time to go all in to save our institutions and democracy.

Republicans elected to Congress are the last bastion that Trump has had to count on, and so far they still stand almost fully behind him. But, not so coincidentally I believe, more and more Republican Senators are now facing difficulty in being reelected.
