WILMINGTON, Del. (AP) – President-elect Joe Biden will likely wear a walking boot for several weeks after breaking his right foot. Biden’s office says the president-elect suffered the injury Saturday while playing with one of his dogs, then visited an orthopedist Sunday afternoon in Newark, Delaware. His doctor, Kevin O’Connor, says a scan found tiny fractures of two small bones in the middle of Biden’s right foot. Fractures are a concern generally as people age, but Biden’s appears to be a relatively mild one based on his doctor’s statement and the planned treatment. At 78 he will become the oldest president when he’s inaugurated in January.
