In the hours before polls closed across America, Democratic candidate Joe Biden made another of his infamous gaffes during a final pitstop in key swing state Pennsylvania

As the polls neared closing in many states, Biden made another one of his infamous gaffes confusing his granddaughter Finnegan with his late son Beau Biden.

“This is my son, Beau Biden who a lot of you helped elect to the Senate in Delaware,” he said, placing his arm around her shoulder.

Biden, who would be the oldest President in US history at 77, then continued to make a mistake when realising his error he instead called Finnegan by her sister Natalie’s name.

“This is my granddaughter, Natalie,” he added, before correcting himself.

“No wait, we got the wrong one.”
