In Febrary 2th, 2017, The Washington Post claimed that President Trump blasted his counterpart Malcolm Turnbull (Australian Prime Minister) over his insistence that the US stand by the deal agreed with former President Barack Obama. The call was scheduled for an hour but Trump cut it short after just 25 minutes when Turnbull tried to discuss topics such as Syria. The President had spoken pleasantly with other leaders including Vladimir Putin but described his call with Turnbull as "the worst so far".
