"Trump better get a better lawyer than Rudy Giuliani," the former Secretary of State said on 'Late Night With Seth Meyers.'

Former presidential candidate and Secretary of State John Kerry spoke about his former high school hockey teammate-turned-special counsel Robert Mueller when he visited Late Night on Tuesday.

Host Seth Meyers shared a photo of Kerry and Mueller sitting next to each other in a St. Paul's High School hockey team photo. The two attended the school together in Concord, N.H.

"He was captain of the team. He was terrific. He was the best athlete in our school," said Kerry of Mueller.

Kerry added that Mueller was a skilled athlete in a number of sports. "Very tough soccer player, lacrosse player and hockey player," he said. "As a lacrosse — he'd smack the other guys, knock them down.

Kerry then joked, "If he didn't knock them down, he'd indict them," which earned a laugh from Meyers and the audience.

Meyers also asked Kerry if he is confident that Mueller will successfully fulfill his current role in investigating possible Russian interference in the 2016 election.

"Let me put it this way. He would savage the defense wherever he played," Kerry said. "Trump better get a better lawyer than Rudy Giuliani."
