Donald Trump Jr has begun selling merchandise that mocks Alec Baldwin, who fatally shot a cinematographer during an on-set incident last week.

Mr Trump has been sharing several Instagram photos and stories since Thursday’s tragic film set incident in New Mexico, where Mr Baldwin was filming Rust outside Santa Fe.

One of the latest stories showed a T-shirt with the words: “Guns don’t kill people, Alec Baldwin kills people”. The Instagram story had a link to Mr Trump’s online website, where the T-shirt is being sold for $27.99
