Rudy Giuliani, who is representing President Donald Trump in the Russia investigation, said Friday he doesn't know for sure if the FBI had an informant in the Trump campaign.
"Here's the issue that I really feel strongly about with this informant, if there is one. First of all, I don't know for sure, nor does the President, if there really was. We're told that," the former New York City mayor told CNN's Chris Cuomo on "New Day."
The New York Times reported Wednesday that at least one government informant met several times with Trump campaign advisers Carter Page and George Papadopoulos. The suggestion that there was an informant has been seized on by several Republican members of Congress and Trump's legal team to raise doubts about the legitimacy of special counsel Robert Mueller's investigation.
Giuliani said Trump's lawyers "were told there were two embedded people in the campaign" and that the Times' report "corroborates what people told us off the record."
But, Giuliani added, "You don't know if they're right or not."
Giuliani also said "if there was an embedded person, that person cleared us because the FBI cleared us."
Trump has pointed to the reporting to criticize the Mueller investigation, and said Thursday that if the report is true, he is a victim of a scandal that is "bigger than Watergate."
WaPo: Trump allies look to reveal FBI source
Giuliani's comments follow a report by The Washington Post that indicated a new wave in efforts to undermine Mueller's Russia probe.
The Post, citing several people familiar with the matter, reported on Thursday that Trump supporters on Capitol Hill and beyond are pushing to reveal one of the FBI's top-secret sources -- the same individual who Trump alleges spied on his presidential campaign.
The FBI's concerns over potential fallout from the exposure of the source's identity has prompted the agency to work for the past two weeks on damage control strategies, The Washington Post reported.
Additionally, the FBI has been working to protect other investigations that the source has been involved with, and is also trying to lessen any potential harm for individuals associated with the source if the identity is revealed, according to The Washington Post.
