Way past time for Repubs to push for impeachment/removal even though they can’t get it past Pelosi.
The 25th Amendment route is always there, but that is entirely in the hands of the President’s party as the designers of the 25th Amendment intended it to be.
But Republicans can and should open investigations into the Biden family criminal enterprise and do so in a way that the MSM can’t ignore or try to explain away as a partisan witch hunt.
Investigations into the Biden family criminal enterprise & judicious application of the Holman Rule are the only recourse if one is serious. Impeachment is the route you take if you just want to posture, wave your hands & virtue signal, because you will never get 67 votes in the Senate for removal.
