President-elect Joe Biden has finalized selections for his incoming Cabinet and top White House positions. Cabinet positions — with the exception of the vice president and White House chief of staff — will require Senate approval, which may face significant delays.

Biden promised to be “a president for all Americans” and build a Cabinet that reflects the country’s diversity. If confirmed, his Cabinet will be more diverse than not only Trump’s Cabinet, but also Obama’s.

Biden has faced criticism for installing women of color in mostly lower-level Cabinet positions while giving some of the most influential positions to White men with long Washington résumés. And for the first time in 20 years, there will no Asian American or Pacific Islander secretary, something lawmakers have expressed repeated concerns about, though Vice President-elect Kamala D. Harris, a daughter of Jamaican and Indian immigrants, will be part of the Cabinet and first in the line of succession.

While Biden’s Cabinet would include some appointees who have served in Republican administrations, it does not include a high-profile member of the opposite party — something he had discussed early on — or holdovers from the previous administration, as Trump and Obama’s Cabinets both did.

Here’s who Biden has selected to fill his Cabinet and other top positions in his administration.
