Lindsey Graham actually said...

Senator Lindsey Graham will now have to testify in a Georgia probe investigating efforts to overturn the 2020 election.

He can raise it. Yes, he can hide behind it for a while.

He had argued that he was exempt from testifying, that he didn't have to testify at all under the Speech and Debate Clause.

I guarantee you Lindsey Graham is looking at the calendar here thinking there will be a new Congress early January of 2023.
