WILMINGTON, Del. - President-elect Joe Biden announced a diverse set of nominees for top diplomatic and foreign policy posts Monday - including the first Latino and first immigrant as homeland security secretary and the first woman as director of national intelligence - as he sought to convey momentum and inevitability in building his administration.

If Joe Biden wins the presidency next month, he plans to fill his national-security team exactly the way Donald Trump didn't -- with officials well-known inside the Washington Beltway who carry resumes full of government experience.
