“I never had the privilege of going to his island, and I did turn it down, but a lot of people in Palm Beach were invited to his island,” Trump said.
“In one of my very good moments, I turned it down. I didn’t want to go to his island,” he added.
So he did go to the island…
He said “never”. Not sure why you’re interpreting it that way.
True or not, he’s clearly asserting that he never went, not that he turned it down once but accepted other times. He’s not admitting to ever having gone.
So when proof comes out that he did, this will be more damning.
