Impeachment is one thing, removal from office is another. Biden will never be removed from office unless the Pubs get a 67 seat majority in the Senate.
Not even then.
Bush I and Bush II were both just as guilty of this and no one ever mentioned impeaching them over it.
Especially Bush II, we had been attacked and he still left the border open.
If the GOP had wanted to stop it, they would have cooperated with Trump instead of fighting against him.
