As for the whistleblower, whose identity is protected by federal law, Graham told Fox host Maria Bartiromo: “The Senate Intel Committee under [Sen.] Richard Burr (R-N.C.) has told us that we will call the whistleblower. Why is it important? I want to find out how all this crap started.”

Graham, a vociferous apologist for Trump, added: “The day of reckoning is coming.”

Graham said he wants to know “if the whistleblower is a former employee [or] associate of Joe Biden,” or “was working with people” on Rep. Adam Schiff’s (D-Calif.) staff. Republicans have presented no information that either case is true.
