It's Tramp Night Club (in London) not Trump
The FBI are only going to be interested if he can give information about their investigations, into people implicit in Epstein's illegal activities.
As far as they are concerned Prince Andrew has not commited a crime. He has had concensual sex with a 17 year old girl in New York and the US Virgin Islands.
What is interesting is that Virginia Roberts has accused Prince Andrew of having (concensual) sex with her in London, New York & the US Virgin Islands.
This tells me that the infamous photo is legit. Because if their agenda is to nail Andrew, all she would have to say is he had sex with her at Epstein's home in Florida, where the age of consent is 18
People could well come forward and say their daughter or son was present at the party attended by Beatrice, and Andrew dropped Beatrice off.
But did he pick her up? Woking being only 25 miles from London.
