President-elect Joe Biden campaigned to have a government as diverse as America. After 36 years in the Senate and eight years as vice president, Biden now has an opportunity to tap a broad range of government officials and policy experts to lead the federal departments.

Biden’s campaign declined to discuss prospects for Cabinet posts, saying those decisions would wait until after the election. But speculation during the final weeks of the campaign ranged from former officials from President Barack Obama’s administration to former rivals in the Democratic primaries and even Republicans.

Sen. Kamala Harris, the vice president-elect, told supporters at an Oct. 17 fundraiser that Biden’s Cabinet would reflect the country, with women and people of color in leadership positions.
