Biden fractures foot after fall, will likely be in walking boot 'for several weeks'

President-elect Joe Biden suffered a sprained foot Saturday after slipping while playing with his dog, according to his doctor.

"Initial X-rays are reassuring that there is no obvious fracture and he will be getting an additional CT for more detailed imaging," Dr. Kevin O’Connor said in a statement Sunday following the examination at the Delaware Imaging Network facility at the Omega Professional Center in Newark.

Biden slipped while playing with his dog, Major, and twisted his ankle.

Biden and Vice President-elect Kamala Harris announced on Sunday seven top members of the White House senior communications staff, all of whom are female.

Jen Psaki, who served as communications director during the Obama administration and has been working as a spokeswoman for the transition, will be the White House press secretary 

Kate Bedingfield, who served as the Biden campaign's communications director, will assume the same title in the White House.

Karine Jean-Pierre, who was a senior advisor to Biden's campaign, will serve as the principal deputy press secretary.

Pili Tobar, who was the Biden campaign's communications director for coalitions, will be the deputy White House communications director.

Other hires announced Sunday include Symone Sanders, a senior campaign adviser, who will be the chief spokeswoman for Harris, Ashley Etienne who will be Harris' communications director, and Elizabeth Alexander, who will be first lady Jill Biden's communications director.

Biden is preparing to roll out the names of people on his economic team and sources have told ABC News that he plans to tap Janet Yellen as his treasury secretary, White House correspondent Rachel Scott said on "This Week" Sunday.

"If confirmed, she would be the first woman to hold that job, and she would face a monumental task of not only trying to rebuild the nation's economy but also likely playing a pivotal role in those stalled coronavirus negotiations there on Capitol Hill," Scott told "This Week" Co-anchor Martha Raddatz.

During the "Powerhouse Roundtable" discussion, Raddatz asked ABC News chief business correspondent Rebecca Jarvis about Yellen: "There were several names that were floated. And what do you think it means?"

"Well, Martha, she’s brilliant. She's experienced and has very broad support. The progressives like her but so do Wall Street and corporate America. And she has bipartisan support. She also has a huge task in front of her," Jarvis said, referring to the ongoing pandemic.

"And while President-elect Biden has been calling for more stimulus and additional stimulus plan, that's something she has also been calling for because of the fact that this recovery that we're in the midst of is still on extremely fragile footing," she added.
