That’s just untrue given they didn’t have the house or senate in 2017.

They didn’t even spend 2019 doing it, even after the Mueller report. When they did impeach him it was on the narrowest possible scope and they got 1 bipartisan vote for removal.

And that’s before the second impeachment which had several Republican backers in the house and senate.

You are confusing congress with democrats as a whole. The democrats I know who are deep in the left wing good right wing bad partisan politics were looking for excuses to impeach Trump all along.
