Axios: “President-elect Joe Biden on Monday unveiled his nominations for top national security positions in his administration, tapping former Secretary of State John Kerry as his climate czar and former deputy national security adviser Avril Haines as director of national intelligence. Haines, if confirmed, would make history as the first woman to oversee the U.S. intelligence community. Biden also plans to nominate Alejandro Mayorkas to become the first Latino secretary of the Department of Homeland Security.”
