The footage was taken during the Democratic Primary in 2019 and shows Mr Biden declining to comment to the British broadcaster. The journalist asked the President: “Mr Biden, a quick word for the BBC.” He replied: “The BBC? I’m Irish.”
The footage has re-emerged amid a reported row between the President and Prime Minister over the Northern Ireland peace deal.
According to reports, Mr Biden’s administration had accused Boris Johnson’s Government of “inflaming” tensions during an ongoing dispute between the UK and EU over the implementation of the Northern Ireland Protocol.
Mr Biden is said to only be about five-eighths Irish, but is known to play up his Irish heritage.
Earlier this week, White House National security adviser Jake Sullivan told reporters: “President Biden has been crystal clear about his rock-solid belief in the Good Friday Agreement as the foundation for peaceful co-existence in Northern Ireland.

A spokesperson for the Prime Minister also insisted President Biden did not “rebuke him”.
On Thursday, Mr Johnson described working with his US counterpart as “a big breath of fresh air” after the pair met face-to-face.
Joe and Jill Biden met with Boris and Carrie Johnson ahead of the G7 summit this weekend.
Mr Johnson said: “It’s wonderful to listen to the Biden administration and to Joe Biden, because there’s so much they want to do together with us, from security, NATO, to climate change.
“And it’s fantastic, it’s a breath of fresh air.”
