Mr Trump has promised throughout his campaign to build a wall along the US-Mexico border, and to deport some 11 million immigrants living illegally in the US if elected.
He has also proposed a temporary ban on Muslims entering the United States.
Mr Trump has also traded words with Pope Francis, after the pontiff described his views on immigration as "not Christian".
The presidential hopeful has also said that he no longer cares about his Doonbeg golf resort in Co Clare.
