Donald Trump Jr is capitalising on the tragedy that took place on the set of Alec Baldwin movie Rust by selling merchandise mocking the actor for the fatal accident.
The eldest child of the former US President promoted a new T-shirt featured on his website that reads: 'Guns don't kill people, Alec Baldwin kills people'.
The item, which is on sale for US$27.99, was photoshopped onto Baldwin in one particularly egregious post on Donald Jr's Instagram Story.
"Screw all the sanctimony I'm seeing out there. If the shoe was on the other foot Alec Baldwin would literally be the first person pissing on everybody's grave trying to make a point. F**k him!" Donald Jr wrote in a follow-up Instagram post, according to the Daily Beast.
Baldwin, an anti-NRA activist who has campaigned for tighter gun laws in the US, has said he's "heartbroken" over the incident, in which cinematographer Halyna Hutchins was killed when a live round was fired from a prop gun that the actor was told was "cold" - meaning not loaded with ammunition.
An investigation continues into the shooting, which also injured director Joel Souza, with court records showing the probe includes the movie's assistant director David Halls and armourer Hannah Gutierrez.
Meanwhile, a number of right-wing pundits have celebrated the tragedy due to Baldwin's comedic impressions of Donald Trump on Saturday Night Live and the actor's views on gun control.
Controversial commentator Candace Owens called the incident "poetic justice" for Baldwin after he "spent four years painting Donald Trump and his supporters as evil murderers" in a since-deleted tweet.
Gun rights activist and Republican representative Lauren Boebert also made light of the incident, referring to a tweet written by Baldwin amid the Black Lives Matter movement in which he said he would make bright yellow t-shirts that read: 'My hands are up, please don't shoot me.'
"Alec Baldwin are these still available? Asking for a movie producer..." Boebert tweeted, tagging the actor.
