The incident, where Joe Biden appeared to freeze on stage after giving remarks at a star-studded fundraiser in Los Angeles over the weekend is trending online.

The viral video captured former president Barack Obama and Biden waving and smiling while receiving a standing ovation in the Peacock Theater in downtown Los Angeles.

It was gathered by Hobnob News reports that Biden applauds and gives the audience a thumbs up but then he stops moving and just stares for several seconds.

Apparently, Obama noticed what was going on and quickly took Biden by the wrist and gave him a gentle push along, after which Biden appeared to snap out of it.

The rather confusing incident is the latest in a series of episodes that have plagued 81-year-old Biden raising fears over his physical and mental well-being.
