President Donald Trump appeared to doze off in the front row of his own UFC birthday celebration, handing critics fresh ammunition and reigniting calls for his removal from office.

Footage circulating from UFC Freedom 250 on the White House South Lawn shows Trump, who turned 80 on Sunday, seated beside UFC chief Dana White with his eyes closed and his head slumping to one side, according to the Mirror and various observers.

Anti-Trump commentator Ed Krassenstein pounced on the clip. "How does this even happen?" he wrote, sharing video of the apparent nap. "Trump appears to have fallen asleep at the UFC event at the White House? 25th Amendment Now!"

The progressive account Call to Activism amplified it as "BREAKING," announcing that Trump "HAS FALLEN ASLEEP AT HIS 80TH BIRTHDAY UFC FREEDOM 250 EVENT."

The moment drew notice from fight fans, too. One MMA account, MMA Joey, claimed Trump "fell asleep during the Bo Nickal fight" and that White "had to slap him" to wake him during the finish, though that version of events could not be independently confirmed.
