So imagine this:

POTUS declassifies a huge stack of documents on his last day. They didn't get released through the agencies... but there's nothing to say the POTUS can't leave with a copy of the stack of documents in his own personal moving truck which was seen leaving the White House...

At his second impeachment, he could just bust out all the intelligence documents that prove Obamagate, prove he won the election, prove he didn't provoke the capitol breach, and prove that the people impeaching him are actually the ones who set up the crime they're impeaching him for.

How's that for an epic counterpunch?
