US President Joe Biden has come under fire after being caught dozing off during a Memorial Day service honoring fallen military personnel. The video of Biden’s apparent nap, first posted on social media, has sparked outrage among some social media users who accuse him of disrespecting America’s fallen heroes. Biden, who has previously been referred to as “sleepy Joe” due to his age and occasional gaffes, has been criticized for his behavior during the solemn event.
