Ex-bureau boss Comey should be prosecuted if FBI snooped on Trump campaign: Rudy

President Trump on Thursday questioned whether the Obama FBI “spied” on his presidential campaign, on the heels of an extensive report on the Russia investigation's origins that said a government informant met several times with Trump's former advisers.

Rudy Giuliani, a member of the president's outside legal team, also told "Fox & Friends" that former FBI Director James Comey "should be prosecuted" if his bureau spied on the campaign.

The fiery statements came on the one-year "anniversary" of Special Counsel Robert Mueller's investigation, which picked up where the bureau left off. The New York Times sought to give a definitive accounting Thursday of the original investigation -- and in the middle of their report, revealed that officials confirmed "at least one government informant met several times with Mr. [Carter] Page and [George] Papadopoulos," both former campaign advisers.

This explosive line is sure to fuel Republican efforts on Capitol Hill to review records relating to an unidentified FBI source -- and his or her role in the Russia probe.

"Wow, word seems to be coming out that the Obama FBI 'SPIED ON THE TRUMP CAMPAIGN WITH AN EMBEDDED INFORMANT.' Andrew McCarthy says, 'There’s probably no doubt that they had at least one confidential informant in the campaign. 'If so, this is bigger than Watergate!" Trump tweeted Thursday.
