WILMINGTON, Delaware — President-elect Joe Biden will likely wear a walking boot for the next several weeks as he recovers from breaking his right foot while playing with one of his dogs, his doctor said. Biden suffered the injury on Saturday and visited an orthopedist in Newark, Delaware, on Sunday afternoon, his office said. “Initial x-rays did not show any obvious fracture,” but medical staff ordered a more detailed CT scan, his doctor, Kevin O’Connor, said in a statement.
