Story highlights Phone call with Peña Nieto came seven days after Trump entered office

Call shows a President working through the complicated nature of bilateral US relationships

Washington (CNN) President Donald Trump boasted about his election victory, pressured his Mexican counterpart to remain quiet about a border wall and called New Hampshire a "drug-infested den" in a phone call with Mexican President Enrique Peña Nieto, according to a transcript of the conversation revealed on Thursday by The Washington Post.

The transcript of Trump's conversation with Mexico's leader was one of two phone calls revealed on Thursday, which provide a rare glimpse into the private conversations of a new US President testing his negotiating powers on foreign counterparts.

The January 27 phone call with Peña Nieto came seven days after Trump entered office. In it, he focused mainly on issues of trade and immigration, with contentious moments coming in his insistence that Mexico will eventually pay for a wall along with US southern border. Peña Nieto has insisted publicly his country will not pay for the wall's construction, but Trump demanded he cease making that claim.

"You cannot say that to the press," Trump said on the phone call. "The press is going to go with that and I cannot live with that. You cannot say that to the press because I cannot negotiate under those circumstances."

A day later, Trump carried out a phone conversation with Australian Prime Minister Malcolm Turnbull, which grew sour when Trump questioning an agreement to take in refugees. The transcript shows Trump growing progressively more agitated, eventually telling his Australian counterpart the call was the worst of the day.
