Could Biden order Trump’s execution and win the next election?
That introduces all sorts of timeline issues because you can’t impeach someone who isn’t in office anymore. It stands to reason that resigning, or ending your term, shouldn’t immediately prevent prosecution since often these kinds of cases take years to put together even with a congress that wanted to impeach. Hell, the evidence of illegal actions may not have even come out until after they resigned, in which case congress would never have an opportunity to hold them accountable.
Is impeachment the only thing the House can do? They can’t enact any other kinds of legislation? Current legislative efforts not-withstanding.
They aren’t part of the justice branch, so their ability to deal with criminal situations is very limited.
See, you say they can’t impeach someone who isn’t in office, I’m pretty sure they actually can but usually just don’t bother because there didn’t used to be much point.
No, you actually can’t. Impeachment is literally the act of removing them from office.
