Delaware Attorney General Beau Biden (D) bowed out of a fundraiser on doctor’s orders Monday, but his father told supporters not to worry — the younger Biden is feeling well enough that the two spent the morning at the driving range.

Vice President Joseph Biden stood in for his son at the Philadelphia event for his re-election campaign, according to a pool report. The younger Biden is recovering from a mild stroke he suffered two weeks ago.

The vice president said his son is healthy and eager to return to work. They spent the morning “pounding golf balls in the mist,” he said, adding that his son later walked the two miles home from his doctor’s office, where he went for blood tests.

Beau Biden’s wife, Hallie, also attended the fundraiser, saying her husband “wanted you to know he’s feeling great tonight and wishes he could be here.”

About 100 people attended the event. The Biden campaign declined to disclose ticket prices for the fundraiser or to say how much was raised.
