Mr Trump told reporters on Friday that he had given Mrs May advice about how to deal with the European Union that she found too "brutal".
She added: "But the legacy of Brexit can not be a hard border between Northern Ireland and Ireland that unpicks the historic Belfast Agreement".

She acknowledged some MPs had concerns about her plan for a "common rule book" with the EU for goods and customs traded within what she called a new "UK-EU free trade area".
Baker, who was a junior minister under Davis, claimed the Brexit Department was little more than a "Potemkin structure to [distract from] what the Cabinet Office Europe unit was doing for the Prime Minister".
