Trump’s trip to France followed his state visit to the United Kingdom—and a short visit to Ireland Wednesday, where Trump met with Irish Prime Minister Leo Varadkar. During their brief encounter, Trump said he believed Brexit would be a boon to the Irish Republic—and compared Ireland’s soft border with Northern Ireland to his plans to expand the wall between the U.S. and Mexico.

President Donald Trump: “I think that will all work out. It will all work out very well. And also for you, with your wall, your border. I mean, we have a border situation in the United States, and you have one over here.”

Public opposition runs deep against any new border controls in a post-Brexit Ireland.
