Vice President Mike Pence said he is "more than willing" to sit down for an interview with Special Counsel Robert Mueller.

In an interview that aired Sunday on CBS’ "Face the Nation," Pence said that he has "fully cooperated" with Mueller's team over the past year and would be "more than willing to continue to provide any and all support" to aid the investigation.

He said Mueller had not requested an interview, but he will continue to provide "any and all information" to the special counsel.

Pence's remarks come amid the ongoing back and forth between Mueller and President Trump's legal team over an interview with the president.

Mueller and his team are investigating Russian interference in the 2016 election and possible collusion between the Trump campaign and Russia, a probe that Trump has repeatedly slammed as a "witch hunt."

On "America's Newsroom" on Monday, Fox News senior judicial analyst Judge Andrew Napolitano said Pence's willingness to cooperate with Mueller's team is a sign that he doesn't believe the investigation is a "witch hunt."

"He thinks it's a legitimate investigation, or he wouldn't be cooperating with it," Napolitano said.

"It also tells me that he's about the staunchest supporter that the president has, and he basically wants to go there and say, 'I was there, and I didn't see anything wrong,'" Napolitano added.

Despite that, he warned that it is "dangerous" for anyone to volunteer to go under oath with federal prosecutors if they are not obligated to do so.

He reiterated a point he has made in the past: It would be unwise for Trump or Pence's legal counsel to allow them in an environment where one slip-up or minor contradiction could mean a perjury charge.

"If you were to ask me, I would say the potential for that is great and grave, and you should stay away from this environment."

He also said that prosecutors will view Pence's offer to sit down with Mueller "suspiciously."

"They are very suspicious of this kind of volunteerism," Napolitano said. "When someone says, 'Hey, let me come and talk to you,' or, 'Put me before the grand jury,' they are suspicious of it, even if that person is a lawyer who happens to be the vice president of the United States."
