Blinken’s appointment made another longtime Biden aide, Jake Sullivan, the top candidate for his U.S. national security adviser, the person said. Bloomberg News earlier reported the expected nomination.
Joe Biden will pick veteran diplomat Antony Blinken as U.S. secretary of state, a person close to the president-elect’s team said on Sunday, adding that an announcement is likely on Tuesday.
Blinken is a longtime Biden confidant who served as No. 2 at the State Department and as deputy national security adviser in President Barack Obama’s administration, in which Biden served as vice president.
