Well of course... however when one licenses through an outfit like ASCAP or BMI or SESAC then one has to agree to certain stipulations about how these outfits do it. They can’t be being jerked around by either artists or customers.
If the copyright owner has agreed that ASCAP may license it, and ASCAP then licenses it to Trump under nondiscriminatory terms, then the copyright owner can bay at the moon. He has no legal legs.
Isn't license implied? Trump would be required to report usage of course. It's been a while since I worked for record labels.
