"Well it sure sounds like he knew something. You know, I mean this man is a former federal prosecutor, worked for the Justice Department. If somebody slipped him some information there, I mean, that is amazing," Moore told CNN on Thursday.

Giuliani said in an interview last week that there is "a surprise or two that you are going to hear about in the next few days" that will "turn this around."

Two days later, FBI Director James Comey told lawmakers that his agency found in an unrelated probe new emails "pertinent" to its investigation into Clinton's private email server and whether the former secretary of State mishandled classified information. 

The Trump campaign on Thursday said Giuliani was not serious when he was making that prediction.

“Rudy was just having fun,” spokesman Jason Miller said. “To keep the other side on their toes.”

However, Giuliani suggested he may have known something in advance. 
 
Pressed by Fox News host Steve Doocy to elaborate on whether he knew the FBI's announcement was coming, Giuliani said that he had heard about the prospect.
 
"I did nothing to get it out. I had no role in it. Did I hear about it? You're darn right I heard about it, and I can't even repeat the language that I heard from the FBI agents."
 
In his interview, Moore blasted Comey about the email scandal, saying the significance of the investigation has been blown out of proportion. 
 
"I think someone should be raising questions about him and why this happened and why he did it on Friday night. And it's got everybody in this sort of, tornado of the emails. ... What about the emails, really? I mean truly really, this is — we have huge issues facing the country. If you are going to put a sociopath in the White House because, oh, you didn't like how she did here emails, this is something seriously wrong," said the filmmaker.
