Mr. Biden, who had been recovering from the coronavirus at his Delaware beach home, has been mostly out of sight since last week.
He announced his decision to drop out of the race in a letter posted on X.
On Monday, Mr. Biden called into a meeting led by Ms. Harris at the Wilmington, Del., headquarters of what used to be their joint campaign and insisted that he would be “fully, fully engaged” in helping to get her elected.
