Video has emerged of Joe Biden seemingly struggling to walk off the stage following a speech at an UN event on Wednesday evening.
The US President, 79, gave a speech at the Global Fund Conference earlier in the week which was held in New York and is aimed at fighting AIDS, HIV, malaria and tuberculosis.
As Mr Biden ended his speech, he attempted to walk off stage before stopping and looking around to find the exit.
After appearing unsure as to how to walk off the stage, Mr Biden then hovers at the back as the speaker thanks the US President.
The speaker said: “At the end of such a momentous event, the word ‘thank you’ seems kind of inadequate.
“But for all the millions whose lives will be saved, for communities where lives will be transformed – thank you, President Biden.”
Mr Biden has previously faced questions over his health but in a recent interview in the US, he shot down any debate as to his capability to lead the country.
Asked by 60 minutes host, Scott Pelley, what he thought about those who question his ability, Mr Biden said: “If you think I don’t have the energy level or the mental acuity, then-- then, that’s one thing.
Before adding: “I don’t, when I sit down with our NATO allies and keep ‘em together, I don’t have ‘em saying, "Wait a minute, how old are you?’”
He then stressed that he was mentally “focused” to continue the job at hand.
