I agree with dhuey - and cigars, well, those re invitations to confiscation at this time. CDs, DVDs, posters, books, art, etc. are fine; rum, cigars - no dice. And certainly, if I chose to make the attempt, I would not lie about possessing these - especially if one has Global Entry or the like.

It is possible you could get a curmudgeonly CBP agent with political beliefs who could choose to be nasty - I have seen this over the years, whether it is about Cuba or something else. I think that's the equivalent of what I got in Cuba, and why I got exit stamps in my US passport.
