Rep. Peter King (R-N.Y.) discussed the chance that an ISIS-inspired terror attack could occur in the U.S.

The FBI and the Department of Homeland Security issued an intelligence bulletin, warning that an attack could happen over the upcoming 4th of July holiday weekend.

King told Megyn Kelly that behind the scenes, law enforcement agencies that are monitoring this situation are very concerned.

"People should be concerned," King said. "ISIS has called for attacks during Ramadan. This July 4th occurs during Ramadan."

He added that this is "the most concerned" he has seen the FBI, the DHS and local law enforcement agencies since 9/11.

"If American people see something, say something," King stated. "I think that's especially true for people in the Muslim community, because that's where the threat is going to come from. I'm really calling on, if they know anything at all, out of the ordinary, let the police know because we're talking about potential life and death here."
