Secretary of Defense James Mattis met President Trump's new national security adviser, John Bolton, at the Pentagon Thursday afternoon, and he broke the ice with a joke.

"It's good to finally meet you," Mattis said as the two walked up the steps of the Pentagon. "I heard you're actually the devil incarnate, and I wanted to meet you."

Bolton responded by laughing as they entered the building.

Mattis is known for his sometimes colorful rhetoric. He once reportedly advised U.S. Marines, "Be polite, be professional, but have a plan to kill everybody you meet."

In an interview on CBS' "Face the Nation," host John Dickerson asked Mattis, "What keeps you awake at night?"

He quickly responded, "Nothing. I keep other people awake at night."

Trump announced on Twitter last week that Bolton, a former U.S. ambassador to the United Nations, would replace Gen. H.R. McMaster as national security adviser effective April 9.

I am pleased to announce that, effective 4/9/18, @AmbJohnBolton will be my new National Security Advisor. I am very thankful for the service of General H.R. McMaster who has done an outstanding job & will always remain my friend. There will be an official contact handover on 4/9. — Donald J. Trump (@realDonaldTrump) March 22, 2018

"It's obviously a great honor. It's always an honor to serve our country, and I think particularly in these times internationally," Bolton told Martha MacCallum on "The Story" after the news broke.
