Sen. Lindsey Graham (R-S.C.) joined Sean Hannity Wednesday to discuss ongoing efforts to get to the bottom of the Justice Department and FBI's handling of the Russia investigation and Hillary Clinton email probe.

Graham, chairman of the Senate Judiciary Committee, has previously vowed to probe a range of different questions, including if the counterintelligence investigation was a back door way of spying on the Trump campaign and if a FISA warrant to spy on a Trump associate was illegally obtained using the infamous anti-Trump dossier.

He noted that Attorney General William Barr has assembled a team to conduct its own investigation of the FBI's Russia probe.

"There's no doubt they were spying on Trump's people in [the] campaign," Graham said. "The question is: Was it lawful?"

He said if the warrant to surveil Trump campaign aide Carter Page was based on the dossier -- which was unverified political opposition research funded by the Hillary Clinton campaign and the Democratic National Committee -- it was not lawful.

"And I don't know why they didn't tell Trump about people on his campaign working for Russia if they really believe that," Graham said.

He added that he also still wants to find out whether Clinton was exonerated by the FBI in 2016 due to "political bias."

"How could Clinton get away with all of this and not have anything, no charges at all, when the average person would probably be in jail now? I think it has a lot to do with political bias," Graham said.
