We all saw that trump wants airports named after him as part of the deal with the bridge to Canada. turns out that's a huge grift too. his lawyers failed trademark patents last week for several versions of his name on airports. Why? So after he extorts people into naming airports after him, he can charge them licensing fees, they even trademarked the names for merchandise.
So he wans them to rename Dulles as Trump airport, they will then have to pay him a licensing fee, and then any t shirts or merch they make he will get a cut of that too
