Incoming White House chief of staff Ron Klain said earlier Sunday that Biden intended to begin revealing members of his Cabinet Tuesday.

Blinken is expected to be among the first nominations, people familiar with the matter said, with Biden intent on sending a signal that rebuilding America's alliances is one of his top priorities.

The president-elect is also expected to name Jake Sullivan, another close aide of his, as national security adviser, and Linda Thomas-Greenfield, a 35-year Foreign Service veteran, as his ambassador to the U.N.

Antony J. Blinken began his career at the State Department during the Clinton administration.
