President-elect Joe Biden unveiled his picks for several top economic positions yesterday, including former Federal Reserve Chair Janet Yellen as his nominee for Treasury Secretary, setting the stage for a more diverse White House.

While Biden's transition to the White House appeared to be hitting its stride, the president-elect was hobbling after fracturing his foot while playing with his dog on Saturday.

Biden named leading members of an economic team that will have to combat the crushing blows to US workers and businesses from the coronavirus pandemic.

In contrast to Trump, who largely picked white men for key positions, Biden's early appointments were shaping up to be highly diverse, including an all-women communications team unveiled on Sunday night.

Biden nominated Janet Yellen, who was the first woman to chair the Federal Reserve, as his Treasury secretary, and Adewale Adeyemo, who would be the first Black deputy Treasury secretary.

Other members of his economics team include Neera Tanden, chief executive of the progressive Center for American Progress think tank, as director of the White House Budget Office, who would be the first woman of color to lead that agency.

Earlier, Biden also tapped campaign staff and advisers to lead an all-woman communications team, naming campaign spokeswoman Kate Bedingfield as White House communications director and veteran Democratic spokeswoman Jen Psaki as press secretary.

"I am proud to announce today the first senior White House communications team comprised entirely of women," Biden said.

He and and Vice President-elect Kamala Harris also began receiving classified briefings that are an essential step toward taking control of national security.
