Rep. Trey Gowdy (R-SC), the chairman of the House Oversight Committee, said on Tuesday that the FBI’s use of an informant for the Trump campaign in 2016 was appropriate, joining top Democrats in disputing President Donald Trump’s characterization of the informant as a spy.

“I am even more convinced that the FBI did exactly what my fellow citizens would want them to do when they got the information they got, and that it has nothing to do with Donald Trump,” Gowdy said during an interview on Fox News.

In recent days, Trump has parroted misleading claims about the FBI’s use of the informant as part of its counter-intelligence investigation into Russia’s interference in the 2016 election, dubbing the individual a “spy” and referring to the controversy as “Spygate.”

Gowdy’s comments were significant because the former federal prosecutor participated in a classified briefing about the informant last week that was conducted by Deputy Attorney General Rod Rosenstein and FBI Director Christopher Wray.
