Mayorkas will never be removed from office. No democrat will, not even if there was incontrovertible video evidence of him/her stealing a Kia in downtown D.C. and then using it to ram into a pot shop for a late night fix.

I agree he won't be removed from office. I don't think the GOP has the votes to even impeach him. Again, no cabinet official ever has been removed - and only one has ever been impeached.

The reason why is fairly obvious. Unlike judges or elected officials, cabinet officials can be fired. Any cabinet official who had actually committed any personal misconduct sufficient to actually support a vote for impeachment would certainly be fired/asked to resign by the President. There's little reason to stand by a cabinet official who's demonstrably done something wrong - you can always get a new person who would come in and do the job the exact same way, but without the wrongdoing baggage.

Mayorkas is being subject to this because Republicans in Congress don't like the way he's doing his job and the way he defended the Administration's policies, not because there's any evidence that he's done anything illegal. There's nothing new about that. In fact, I don't think you could find a single Administration in U.S. history where there wasn't some Department that the opposition party thought was being cocked up beyond belief. But that's never resulted in an impeachment proceeding against the official heading that Department, for the obvious reason that: i) that's not a ground for impeachment; and ii) if the official isn't personally committing crimes, the President can (and likely will) just replace him with someone who shares the same approach to running the Department.
