WASHINGTON — President-elect Joe Biden on Saturday filled out his State Department team with a group of former career diplomats and veterans of the Obama administration, signaling his desire to return to a more traditional foreign policy after four years of uncertainty and unpredictability under President Donald Trump. Biden will nominate Wendy Sherman as deputy secretary of state and Victoria Nuland as undersecretary of state for political affairs — the second- and third-highest ranking posts, respectively.
