Senate Judiciary Committee Chairman Lindsey Graham (R-S.C.) said on Tuesday that he has started closed-door interviews as part of his deep dive into the surveillance courts and the FBI’s Russia probe. Graham confirmed to reporters that he has started the depositions, then escaped into a Senate elevator. Graham is using his gavel to probe the Foreign Intelligence Surveillance Court (FISC) surveillance warrants involving Trump campaign associate Carter Page and the FBI’s handling of the investigation into Russia's election meddling and the Trump campaign. He’s requested testimony from more than 20 current Justice Department and FBI officials.
