According to AP, shortly before his meeting with Theresa May, President Donald Trump spent one hour talking on the phone to the president of Mexico, Pena Nieto, amid "rising tensions" over Trump's proposed wall along the border. Two administration officials confirmed Friday's call.

According to Reuters, citing the Mexican government, the conversation between the two presidents included discussions on the trade deficit between the US and Mexico, and also discussed the need for both to work together to stop trafficking of drugs and illegal arms. Furthermore, the president agreed not to speak publicly for now on the "controversial" subject of payment for the border wall. During the Theresa May press conference, Trump said that the call was "very good" and "friendly", and has a "very good relationship" with Nieto, but added that "Mexico has made us look foolish" and the trade deals will be renegotiated.
