A couple of things to think about:
1. Trump is a businessman. If you are selling shirts bearing his 'image and likeness' without paying him, you may hear from his legal people. Of course, I am not an attorney, and this comment should not be considered legal advice.
2. The message 'can't dump the Trump' is ambiguous. Is he like a crazy ex-girlfriend you can't get rid of? Is he like herpes? You can't get rid of herpes, either. Also, the word 'dump' brings to mind defecation. Are you saying Donald Trump is a turd that's stuck in transit?
Just doing my part to be the Dog turd in your chocolate pudding, new guy.
