The president fell at the conclusion of his remarks at the Air Force Academy's graduation ceremony, appearing to trip over a sandbag.
Twitter users suggested that the fall could be a sign that Biden is not well.
"It's time to invoke the 25th Amendment," Founder and Chairman of ACT For America Brigitte Gabriel wrote on Twitter.
Others said that mainstream media would not cover the fall as comprehensively as they did for former President Donald Trump.
