Justice Department Inspector General Michael Horowitz will testify before the Senate Judiciary Committee on Dec. 11 about his investigation into alleged abuses of the Foreign Intelligence Surveillance Act (FISA) during the Russia probe, Chairman Lindsey Graham (R-S.C.) announced Monday.

Why it matters: Horowitz's highly anticipated report is expected to explore, among other things, whether the FBI's court-ordered surveillance of former Trump campaign aide Carter Page was properly handled. Trump allies hope that Horowitz's report, as well as a separate investigation into intelligence collecting led by prosecutor John Durham, will undermine the findings of the Russia investigation.
