Speaker Paul Ryan (R-Wis.) on Wednesday pushed back against President Trump’s “spygate” claims, siding with Rep. Trey Gowdy’s (R-S.C.) defense of the FBI’s investigation into Trump’s campaign and Russia.

“Chairman Gowdy’s initial assessment is accurate, but we have more digging to do,” Ryan told reporters during his weekly news conference.

A week after a closed-door briefing on the bureau’s use of an informant in the investigation, Gowdy told CBS News that he had seen no evidence to support Trump’s claims that a “spy” was improperly inserted into his 2016 campaign.
