Sen. Lindsey Graham refused to talk about anything except a new report that former FBI Director James Comey knew a key document in the Hillary Clinton email investigation was bogus.

"I want to get back to the idea that the FBI director's decision to jump into the election and say that Hillary Clinton did not commit a crime but she was pretty much incompetent was based on a fake email from Russia. He never told anybody in Congress, which is stunning," Graham, R-S.C., said on "State of the Union," repeatedly redirecting Bash's unrelated questions back to the report.

"And at the end of the day, if the Russians are this sophisticated, we need more sanctions yesterday against the Russians. Or if, in fact, this is a true email, I want to see the email," Graham added.

Graham said the FBI intervened in July 2016 because Comey believed the Justice Department had been compromised after hearing about a fake email the Russians had created. The email appeared to be between two top Democratic officials referring to an email between a Clinton campaign aide and former Attorney General Loretta Lynch.

The Senate Judiciary Committee member said, despite appearing before his committee and speaking with the Senate and House intelligence committees, Comey never shared this "highly explosive" information that he thought the Justice Department was compromised and that's why the FBI ended the Clinton investigation last July.

"He basically took over the Department of Justice's job based on a fake email from the Russians. That to me is a stunning story. From Congress' point of view, he never told us it was fake. So, he needs to be held accountable and if it were not, if it is not fake, we need another investigation," Graham said.
