The Republican-controlled House and Senate could end this today. Like, right now. They could put a complete stop to it. They could remove Trump and Vance simultaneously, resulting in Mike Johnson - a total scumbag, but not one who wants to obliterate the United States - becoming the president.
Right now. They could do it right now. But they won't.
We have impeached him already. You mean convict and remove from office which is a step after impeachment and requires 2/3 of Congress to convict in order to remove him.
