Mr Biden has spoken about being a proud Irish-American Catholic in the past and has also recently got in touch with his roots in Ireland. He visited the country to trace his ancestry and his Irish cousins also flew to the US to help with his campaign. Irish officials are said to be hoping this will be a boost for trade talks between the UK and EU in the event Mr Biden is elected president after tomorrow's election.
The Irish border has been a contentious issue throughout the negotiations, most recently due to the UK Government announcing it wanted to make changes to the previously agreed Withdrawal Arrangement.
The former vice-president added that there would be no US-UK trade deal if the UK pushed through Prime Minister Boris Johnson's Internal Market Bill, due to concerns it could jeopardise all the protections against a hardened border between the north and south.
He tweeted: "We can't allow the Good Friday Agreement that brought peace to Northern Ireland to become a casualty of Brexit.
“Any trade deal between the US and UK must be contingent upon respect for the agreement and preventing the return of a hard border."

But some social media users do not think Mr Biden should weigh in on Brexit talks, which are currently continuing in Brussels.
One user wrote: "He can stay far away from Ireland, thank you very much."
Another added: "Too late we have left. Roll on December 31, only good thing about 2020."
A third simply added a warning for Mr Biden to not get involved.
They said: "Stay out of their business."
