Rudy Giuliani issued a cryptic warning Monday that whoever convinced the FBI to pursue the Russia collusion investigation into the Trump campaign will soon be outed, as he also called on President Trump's "shameless" critics to apologize for their claims in the wake of the Mueller report's conclusion.
Speaking with "Fox & Friends" after the report turned in no evidence of a Trump-Russia conspiracy, Giuliani was asked whether someone tricked the FBI into opening the original investigation.
"Yes, yes, yes -- and you're going to find out, believe me, who it was," Giuliani, Trump's personal lawyer and the former New York City mayor, said.
