US President Donald Trump is expected to sign an executive order on AI and cybersecurity as soon as Thursday, two sources familiar with the matter told Reuters, as pressure grows from parts of his political base to increase oversight of new AI models, such as Anthropic's Mythos.The White House was working to get AI company CEOs to a signing ceremony with President Donald Trump, another source familiar with the planning said.

The order would create a voluntary framework for AI developers to engage with the US government about the public release of covered models, the sources said. Under the framework, the developers would be asked to provide their models to the government 90 days before public release, and also give pre-public access to critical infrastructure providers such as banks, one of the people said.

Such an approach may represent a middle ground among Trump supporters.

MAGA activists, including former Trump adviser Steve Bannon and right-wing political organizer Amy Kremer, have been pressing the White House to require AI developers to submit their most capable models for government security tests.

On the other side of the debate are tech industry supporters such as venture capitalist Marc Andreessen and former Trump adviser David Sacks, who are resistant to mandatory requirements. Sacks in March stepped down from his role as Trump's lead AI official and is now co-chairing the president's tech advisory committee. Trump’s AI policies in his second term have largely reflected the tech industry’s perspective.
