Sen. Lindsey Graham (R-S.C.) told Sean Hannity Monday that he still wants to find out whether Hillary Clinton was exonerated by the FBI in 2016 due to "political bias."

Graham, chairman of the Senate Judiciary Committee, promised further investigations to get to the bottom of a range of different questions about the email probe and how the FBI's Russia investigation started in the first place.

"Was the counterintelligence investigation a back door way of spying on Trump? There’s really no evidence of working with Russia. They just used it as an excuse. Was the FISA warrant obtained unlawfully based on fraudulent documentation to surveil the campaign?" he asked.

He said now that Special Counsel Robert Mueller has rendered his verdict that there was no collusion between Russia and the Trump campaign, it's time to look at how the situation went "off the rails."

"I'm going to use every tool available to me, disclose as much as I can without compromising sources and methods to make sure the public understands how their president could be accused of working with a foreign government when there's really no basis in fact," he said.

Graham said if investigators "used the law for political purposes" and tried to take down Trump after the election, "it's bigger than Watergate."

"I don't know [if they did], but nobody seems to give a damn except me, you and a few other people," he said, arguing the Russians want to "destroy America" and will go after either political party in the future.
