Irish premier Micheal Martin is greeted by JD Vance at the US vice president's residence before a day of engagements to mark St Patrick's Day. He will later meet with President Donald Trump to discuss Ireland's trading relationship with the US. The meeting comes amid concerns about the impact of Trump's protectionist approach on the Irish economy. Other topics that may be raised include the legal status of undocumented Irish citizens in the US and conflicts in the Middle East and Ukraine.
