WATCH LIVE: President-Elect Biden Announces Key Administration Picks

President-elect Joe Biden is formally announcing his most recent nominees and appointments for his incoming administration.

Among his choices are Antony Blinken for secretary of state, Alejandro Mayorkas for homeland security secretary and Avril Haines for director of national intelligence.

Former Secretary of State and former Massachusetts Sen. John Kerry is slated to lead the administration's efforts to combat climate change as special presidential envoy for climate — a role that for the first time ever will sit on the National Security Council. And another person with Massachusetts ties, MIT professor Ernie Moniz, is also on the shortlist for energy secretary.
