Every year the taoiseach makes a trip to the US and has an audience with the president at the White House.
During the trip the Irish leader presents the US president with a bowl of shamrocks, a tradition dating back to the 1950s.
The meeting on Tuesday was dominated with talk about Iran and fighting in the Middle East.
Taking questions from reporters Trump was asked what his message was to Irish people who are paying high energy prices because of the US-Israeli attack on Iran.
“I have a lot of friends from Ireland, they’re very happy that I’m getting rid of… a nuclear power, a nuclear terrorist,” Trump said.
“And as soon as that war is over, which will be soon, your prices are going to drop like a rock. You watch.”
