The acting White House Chief of Staff has said that the Trump administration is not picking sides when it comes to Brexit.

Mick Mulvaney said it was an internal matter for Europe, but added that the White House wants to ensure that the Northern Ireland peace process is protected.

"We just want to make sure that the Good Friday Agreement is respected and that peace accords are kept," he said.

Mr Mulvaney said they receive daily updates on Brexit, and that President Trump has talked to Boris Johnson a couple of times in the last few weeks.

"We watch it from a distance. We're not picking sides, but if we can help we will and we want to," Mr Mulvaney said.

"We're not weighing in but we're not ignoring it either. Right now, we're a very interested observer from the outside."

Separately, Mr Mulvaney said the controversy over the US Vice President's recent stay at Trump Doonbeg was "ludicrous".

Mike Pence spent two nights at Donald Trump's hotel in Doonbeg, Co Clare when he visited Ireland earlier this month.

Democrats have accused him of funneling US taxpayers' money into a Trump business, and the House Oversight Committee has launched an investigation.

Asked about it today, Mr Mulvaney highlighted the fact that Mike Pence has family connections to Doonbeg and dismissed the controversy.

"This is American politics. To a large extent the story is gone already to be replaced by something equally ludicrous tomorrow," he said.

Meanwhile, US Congressman Richard Neal has held a meeting on Capitol Hill with a delegation of civic and business leaders from Northern Ireland.

The group is in Washington to discuss concerns over Brexit.

Congressman Neal is the Chairman of the House Ways and Means Committee, which will oversee any future UK-US trade deal after Brexit.

Ahead of today's meeting, Congressman Neal said his position on Brexit has not changed.

"There will not be a bilateral trade agreement between the US and the UK if there's any threat to the border," he said.
