A top Republican defended his committee releasing the declassified FBI interview with a top source for British ex-spy Christopher Steele and said a forthcoming document would show the bureau misled Congress about the reliability of his anti-Trump dossier.

South Carolina Sen. Lindsey Graham, the chairman of the Senate Judiciary Committee, criticized the former MI6 agent, said Steele’s dossier was compromised by Russian disinformation, and argued newly public FBI notes from a January 2017 discussion with Steele’s “primary subsource” demonstrated the FBI knew the dossier was unreliable but continued to use it anyway. During his interview with Maria Bartiromo on Sunday Morning Futures on Fox News, he also previewed new bureau records to be released in the upcoming week he said would show the FBI misled not just the Foreign Intelligence Surveillance Court about the Steele dossier, but also lawmakers.
