Biden's stumble at Air Force Academy graduation sparks political reactions.

President Joe Biden fell on stage at the U.S. Air Force Academy graduation ceremony in Colorado but quickly got back up with the help of Secret Service agents and an Air Force officer. The 80-year-old president appeared to trip on a black sandbag being used to steady his teleprompter. White House officials confirmed that Biden was "totally fine" after the incident. Biden's age and physical health have been a factor in his reelection campaign, with a recent poll finding that Americans said 62-33% that they thought Biden was not in good enough physical health to serve effectively.
