Actor and comedian Seth Rogen made an unscripted comment about the Silicon Valley moguls in attendance at the Breakthrough Prize ceremony, where he was hosting an award.
Rogen referred to the recent sacking of government departments and agencies by the Trump administration, and the impact that this decision will have on science in the US.
The moguls present included Zuckerberg, who founded the Breakthrough Prize with his wife, and Elon Musk, who spent $300m supporting Trump’s election.
Rogen’s comments saw only light applause from the audience, and the relevant section has since been removed from the YouTube upload of the ceremony.
The Breakthrough Prize is intended to honour innovative researchers in the life sciences, fundamental physics, and mathematics.
