Jordan Rich fills in on NightSide:

President Joe Biden took a tumble recently while biking in Rehoboth Beach, Delaware with the First Lady. He had stopped to talk with a group of reporters and subsequently fell from his bike. The President has also been seen tripping up the stairs of Air Force One and walking with a slow gait. Given the recurrence of trips and falls like this, should we be concerned about the health and well-being of our president?

In addition, Jordan takes calls on other topics.
