President Trump rounded out his first full week as President of the United States with his first meeting with a foreign head of state.

British Prime Minister Theresa May joined Trump at the White House on Friday morning for a chat and a press conference, following which would be a working lunch. May and Trump are said to have discussed trade, security, and the future of the two countries’ relationship.

Another head of state, Mexican President Enrique Peña Nieto was also scheduled to visit the White House to meet with President Trump, but that meeting was scuttled after President Trump’s claims that Mexico would pay for the border wall on which he directed construction to begin in an executive order earlier this week. The White House followed up by threatening a 20 percent tariff on imports from Mexico, though it walked back and said it was just one option to pay for the wall. Trump and Peña Nieto reportedly spoke on the phone for an hour Friday morning, though details of the discussion weren’t made public.
