The questions to Trump and Martin have now ended, with his comments ranging from Iran, Gaza and, interestingly, right up to his view that a united Ireland "will happen" even if "the UK has something to say about it".

Those lines are sure to have reverberations around the UK, particularly in Northern Ireland.

Many unionists, who support Northern Ireland continuing to be part of the UK and oppose reunification, have also been supporters of Donald Trump.

Back in March, during a St Patrick's Day visit to Washington, Northern Ireland's deputy first minister Emma-Little Pengelly - from the Democratic Unionist Party (DUP) - said the president was joking when he referenced promoting a possible "merger" in Ireland.

However, there was no sense he was joking a little while ago in Farmleigh House.

Trump is now asked about Irish reunification.

The president says he does not "want to cause any problems" but says he would "love to see it unified".

He says he has friends on both sides and that it would be a "great feather in everybody's cap" if there was unification.

He says it is "going to happen eventually" and adds that he thinks it would be a "great thing".

He says that the "UK will have something to say about it" but "how can it be bad?"

Trump is now asked what he'd say to people protesting today about his visit in Ireland.

"I haven't seen any protests," he says, before joking: "It's a friendly protest."

He says the US has a "great relationship with Ireland".

It's a "very profitable one for Ireland, less profitable for us to be honest with you," he adds.

Trump is now asked about what he would say to those in Ireland who say the US is facilitating genocide in Gaza and the illegal occupation by Israel of territories in West Bank.

"We put out the fire," Trump responds and adds that the US got all of the hostages taken in the 7 October attack returned to Israel.

He adds that the US has "facilitated a peace of a kind".

Martin interjects and says that he has discussed the need for ongoing humanitarian aid going into Gaza with Trump.

"We'll get that done, definitely," adds Trump.

Trump now takes questions from reporters. The first is on when the Iran war will end.

He replies: "I think very soon... probably right after the midterms."

He reiterates his position that "Iran cannot have a nuclear weapon", calling it "very simple".

"Oil [prices] will come tumbling down when that happens," he says.

Donald Trump is now speaking and thanks the Irish taoiseach. He says the pair have been friends "since the beginning" and they have a great relationship.

The pair share a joke as they speak about the Irish Open, which Trump will be attending later today and tomorrow.

Trump says the leaders have had discussions on trade and that the US has a great relationship with Ireland.

"It has never been as good as it is right now," he says as he thanks the taoiseach for hosting him.

We're currently listening into a sit-down conversation between Taoiseach (Irish Prime Minister) Micheál Martin and Donald Trump.

Martin pays tribute to those who lost their lives during 9/11, and remembers the "bravery and sacrifice" of first responders.

He says he's "particularly pleased" Trump has made it to Ireland for the Irish Open golf tournament, referencing a "very strong sporting relationship" between the two countries.

He also praises the "strength of the economic relationship" between the US and Ireland, saying he is "very pleased" to welcome Trump to Ireland.

Taoiseach (Irish Prime Minister) Micheál Martin and President Trump are now speaking inside Farmleigh House.
