Did the US president have some other place to be?
As the G20 entered its final day in Buenos Aires, a hilarious video has emerged showing Donald Trump shaking hands with Argentina's president Mauricio Macri then wandering off, stage right.
Trump was supposed to pose for photographs with his Argentinean counterpart before a group photo with other G20 leaders, but instead walked away.
An aide began to chase down the US president while Macri sheepishly lingered on stage all by himself.
