The US Vice-President stayed at Trump International Doonbeg for 2 nights last week, despite his official meetings taking place in Dublin.
US State department receipts show almost 600 thousand dollars was paid to JP Ward and Sons - a Limousine company based in County Wicklow.
The US House of Representatives has launched an investigation into the decision for Mike Pence to stay in Doonbeg - a decision which US President Donald Trump has denied any involvement in.
