Trump attorney Rudy Giuliani contradicted President Trump's claims about an informant being planted by the FBI and CIA during the campaign, telling CNN's Chris Cuomo that "I don't know for sure, nor does President Trump, if there really was one."

The backstory: Trump has been tweeting about the growing amount of speculation by conservative writers that a secret "source" from U.S. intelligence was used against the Trump campaign. Axios' David Nather notes that it's worth watching to see if their suspicions are confirmed, but right now they're just suspicions — not evidence. And Giuliani made it clear the White House doesn't have that evidence yet either.

Update: Following this interview, Trump fired off another tweet about the speculation of an implanted informant.
