This is what happened.
Trump showed up late. He wanted Russia in the G7 again to make a G8, but was refused.
There is a picture with Trump being surrounded by other leaders and Germany hovering over him while he sat.
He talked with the PM saying good things.
PM gave him a photo of his dads brothel that was in B.C. Canada. Kind of a troll thing to do. Supposedly it was the start of his dads bussiness in North America or something.
Trump left early from the summit and missed the group photo.
PM said some things about how we will stand up for Canadians after Trump left. Trump didn't like this.
Trump tweets nasty things. Spokespeople say nasty things.
Trump is meeting with NK soon. Didn't like how he was treated at the G7. Basically Trump wanted the G7 leaders to praise him. Say what great person he is for dealing with NK. They instead scolded him a bit. Trump is a sensitive person....
