Speaking to reporters ahead of his meeting on Thursday with Leo Varadkar, the Irish prime minister, Trump said he wants Brexit talks to work out but was surprised at how badly the negotiations have gone, adding that the British prime minister did not listen to his suggestions on how to negotiate.
Mr Trump told Leo Varadkar that he wanted to make the trip during a meeting with the Taoiseach in the Oval Office in the White House on Thursday.
President Trump on Thursday declared that Europe was "being ripped apart" by the chaos caused by Brexit, as the United Kingdom continued struggling to manage a workable exit from the EU.
"She's got to do what she's got to do but I think it could have been negotiated in a different manner, frankly".
He lamented that the country is "being ripped apart" because of a long-standing political crisis that gripped the government and parliament.
"As you can imagine, with everything else going on at the moment, I've barely had time to think about that", Varadkar said, a reference to votes on Britain's exit from the European Union earlier that day.
"We have a different opinion", he said, referring to the president.
During the annual event, the Taoiseach presented the USA president with a bowl of shamrock to mark his St Patrick's visit to Washington DC.
But he insisted: "We are going to have a very strong border very soon", and he praised law enforcement officers catching "thousands of illegal aliens a month".
Mr Varadkar said: "I stand here this morning as leader of my country, flawed and human, but judged by my political actions and not by my sexual orientation or my skin tone or my gender or religious beliefs".
Mr Trump was asked if he was still a Brexit supporter.
Meanwhile, Trump claimed that the United States "will stay right in our lane".
"It wasn't that I was a supporter (Leave), I predicted that it was going to happen", he said.
The Prime Minister has previously revealed that Mr Trump told her to "sue the EU" and "not go into negotiations".
Pence tweeted that he was honored to host Varadkar at his home.
"Last year you and Karen said that my partner, Matthew, would be welcome to join us, and we're both really honored to accept the invitation this year", Varadkar said.
The event saw Varadkar present President Trump with the traditional bowl of shamrock as part of an annual ceremony that dates all the way back to the 1950s.
