Taoiseach begins St Patrick's trip to the US in Texas
The taoiseach has begun his St Patrick's trip to the US with a series of engagements in Texas.

With the Republic's economy supported by thousands of jobs created by US-based multinationals, President Trump's "America First" protectionist policies may also be raised, as might Ireland's controversial tax arrangements with some of those companies.
The ongoing powersharing crisis in Northern Ireland is also likely to feature to the talks.
As well as Austin and Washington DC, the taoiseach will also fulfil engagements New York.
He will also visit a Native American community in Oklahoma.
His meeting with the Choctaw Nation will commemorate the tribe's fundraising efforts for the victims of the Great Famine in the mid 19th Century.
In Austin, the taoiseach will celebrate Irish innovation at the South by Southwest festival and meet the governor of Texas, Greg Abbott.
After further stops in Texas and then Oklahoma, Mr Varadkar travels to Washington DC on Tuesday where he will deliver a foreign policy address to the Brookings Institution.
That evening, the Taoiseach and Senator George Mitchell will be keynote speakers at a congressional event to mark 20 years since the signing of Northern Ireland's Good Friday Agreement peace agreement.
His Washington engagements also include meetings with senior representatives of Irish companies succeeding in the US market.
On Wednesday, the taoiseach will address the annual American Ireland Fund gala dinner.
Keeping with recent traditions, Mr Varadkar's bilateral meeting with Mr Trump on Thursday will be followed by the annual speaker's lunch on Capitol Hill and the ceremonial exchange of a shamrock bowl between the president and taoiseach back at the White House.
On Friday, the taoiseach will be guest of honour at a breakfast hosted by vice-president Mike Pence.
