BOSTON (CBS) — President-elect Joe Biden spoke highly of former Massachusetts senator and Secretary of State John Kerry as he announced Kerry’s role on his National Security Council Tuesday. Kerry will serve as Special Presidential Envoy for Climate.

“For the first time ever, the United States will have a full-time climate leader to participate in ministerial level meetings – and that’s a fancy way of saying he’ll have a seat at every table around the world,” Biden said. “The world will know that one of my closest friends, John Kerry, is speaking for America on one of the most pressing threats of our time. No one I trust more.”
