President Trump invited Ireland's Prime Minister Leo Varadkar to the White House for next year's St. Patrick's Day festivities. Trump invited Varadker during a phone call when he congratulated the leader on his victory. Varadker was named Ireland's youngest and first openly gay leader earlier this month. "We have so many people from Ireland in this country - I know so many of them, I feel I know all of them...But I just wanted to congratulate you, that was a great victory that you had," Trump told Varadker.
