We're guaranteed to have a lot of Biden impeachers returning to Congress that's for sure.
It's hilarious how somehow W and Obama weren't impeached by their opposition. Polarization practically calls for it now.
One of the first acts that the Republican House majority will take will be to impeach Biden, as retaliation for what they perceive as the "partisan witchhunts" against Trump.
Don't see what else they plan on doing
They will pass some symbolic pieces of legislation that won't make it past the Senate, and probably some worthless resolutions.
This might be trivial, but people, or at least commentators, will note the irony that much of Biden's agenda got as far in a Democratic trifecta as those Republican resolutions will.
