The South Florida facility was called Palm Beach International Airport for over half a century until Thursday, when a months-old state law took effect, adding the airport to the growing list of places and things that now bear President Trump's name.

The agreement allows the county to freely use the name "President Donald J. Trump International Airport" for airport signage, merchandise and more. And it explicitly says that Trump "is prohibited from receiving royalties, fees, or revenue from the purchase or sale of any such merchandise by County or airport retailers."

But legal experts told NPR that they see a potential loophole: sales that happen beyond the airport.

Because the license is non-exclusive, Gerben says, Trump could in theory license the airport name trademarks to third parties. And the contract doesn't say anything about restricting those profits.

"So based on my reading of the agreement, it would seem that if [the Trump Organization] wanted to sell merchandise online, that they would be able to do so without any connection to the airport," he says.
