It’s reported Mike Pence is set to enter the race for the White House in 2024.
The former US Vice President is expected to announce his presidential campaign next week.
Mr Pence’s Irish heritage stems from his grandfather, who immigrated from Tubbercurry in Co Sligo to the US in 1923 after previously serving with the Irish Defence Forces during the Civil War.
His grandmother’s parents grew up near Doonbeg, in Co Clare.
Also planning to declare his candidacy next week is former New Jersey Governor Chris Christie.
Both men will be joining an increasingly crowded Republican field to challenge Donald Trump.
