Caputo, a 30-year veteran of Republican political campaigns, made the revelation on Anderson Cooper's prime-time program during a discussion previewing the release of the final Mueller report on Thursday.

ADVERTISEMENT "They're going to become very famous people in America very quickly," Caputo said of White House staffers who may have spoken to investigators on Mueller's team.

"They've all kept their heads down, both former and present White House staffers," he continued. "And now suddenly they're going to be right in the middle of this stage. That's going to be real uncomfortable."

"Lots of weird things are going to start happening. Like, for example, they're going to start getting death threats," Caputo added. "I've gotten 59 of them. I've had two people criminally charged in the last 10 days. So this is going to happen to those folks."

Caputo, who served as communications official for the 2016 Trump campaign in New York, was among those associates who spoke to Mueller's team as it probed possible campaign contacts with Russia. Caputo denied having any contact with Russian officials.

Caputo has spoken about death threats against him and his family before in a statement to the Senate Intelligence Committee in May 2018.

"Forget about all the death threats against my family. I want to know who cost us so much money, who crushed our kids, who forced us out of our home, all because you lost an election," he said at the time. "I want to know because God damn you to hell."
