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

After initial X-rays were "reassuring," a follow-up CT scan showed that President-elect Joe Biden has hairline fractures in his foot following a fall this weekend, his doctor said.

Biden will likely need to wear a walking boot "for several weeks," Dr. Kevin O’Connor, the director of executive medicine at GW Medical Faculty Associates, said in a statement.

“Initial X-rays did not show any obvious fracture, but his clinical exam warranted more detailed imaging," O'Connor said in a statement. "Follow-up CT scan confirmed hairline (small) fractures of President-elect Biden’s lateral and intermediate cuneiform bones, which are in the mid-foot."

Biden fell over the weekend while playing with his dog.

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 slipped while playing with his dog Major, and twisted his ankle on Saturday. Out of an abundance of caution, he will be examined this afternoon by an orthopedist.
