President Trump recently talked Brexit and trade relations with the prime minister of Ireland, while hosting the leader at the White House.
While bilateral relations and Irish undocumented immigrants in the States were on the agenda for Mr Varadkar's Oval Office meeting with Mr Trump, Brexit dominated their talks.
"I will tell you, I'm surprised at how badly it's all gone from the standpoint of a negotiation", Trump said, sounding like he wasn't that surprised at all.
"People often ask me what I felt on Inauguration Day when I raised my right hand", Pence said.
On the prospect of another referendum, he said: "I don't think another vote would be possible because it would be very unfair to the people that won".
US President Donald Trump has again repeated his false claim that he predicted the result of the Brexit referendum the day before it happened.

"It's a very complex thing right now, it's tearing a country apart".
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".
