WASHINGTON (AP) — Joe Biden is filling out his administration with key picks for his national security and foreign policy teams.

John Kerry will lead the incoming administration's effort to combat climate change.

Alejandro Mayorkas will be nominated as the secretary for the department of homeland security.

Biden also plans to nominate Antony Blinken as his secretary of state.

Kerry is a former secretary of state, senator from Massachusetts and Democratic presidential nominee.

Earlier Monday, Biden named two longtime Capitol Hill aides to his legislative affairs team. Reema Dodin and Shuwanza Goff will serve as deputy directors of the White House Office of Legislative Affairs.
