Story highlights #TrumpCup calls on supporters to ask for their drink under Trump's name

Protest comes after a Miami man claims to have been refused service

(CNN) Donald Trump supporters have started asking for their Starbucks drinks under Trump's name as a movement against the coffee giant.

After a viral video showing a Trump supporter yelling at a barista gained traction on Wednesday, other supporters have banded together to protest what they view as political and anti-white discrimination.

The man in the video told the Miami Herald that he was racially discriminated against and that the barista wouldn't serve him because she knew he was a Trump supporter.
