A VIDEO of the president-elect of the United States having a tongue-in-cheek dig at the BBC has gone viral on social media.

Joe Biden, who sealed victory over Donald Trump after winning the crucial state of Pennsylvania, was filmed knocking back an interview with the British broadcaster, citing his Irish heritage.

New York correspondent Nick Bryant requests “a quick word for the BBC” as the Democratic veteran passes through a crowded room.

“The BBC?” Biden responds, before adding with a smile: “I’m Irish.”

The footage dates back to January, when the former vice-president visited Iowa as he campaigned for the Democratic nomination.

Biden's victory came after more than three days of uncertainty as election officials sorted through a surge of mail-in votes that delayed processing.

The president-elect’s lineage can be traced back to Counties Louth, Derry and Mayo.

He has always embraced his heritage, even quoting Irish poet Seamus Heaney during his Democratic Party nomination acceptance speech: “History says, Don’t hope / On this side of the grave. / But then, once in a lifetime / The longed-for tidal wave / Of justice can rise up / And hope and history rhyme.”

Biden added: “This is our moment to make hope and history rhyme.”
