“I’m a pretty hawkish guy, but if the court doesn’t take corrective action and do something about being lied to, you will lose my support,” Graham told DOJ Inspector General Michael Horowitz during a lengthy opening statement. “I know a lot about what’s going on out there to hurt us, and they are real threats, and they are real agents. And they are really bad actors out there. I would hate to lose the ability of the [Foreign Intelligence Surveillance Act] court to operate at a time, probably when we need it the most. But after your report, I have serious concerns about whether the FISA court can continue unless there is fundamental reform.”

The focus of Horowitz’s inquiry was examining allegations of FISA abuses against onetime Trump campaign associate Carter Page related to the FBI’s reliance on a salacious and unverified dossier compiled by British ex-spy Christopher Steele. Horowitz concluded that the FBI’s investigation was filled with serious missteps and the concealment of exculpatory information from the FISA court. The report said at least 17 “significant errors and omissions” were discovered in the Page FISA applications spanning from October 2016 to summer 2017.
