A top White House artificial intelligence policy adviser announced on Saturday that he will depart his role at the end of June, signaling the exit of a key figure in shaping policies for advanced technologies.

"This journey has been the privilege of a lifetime," adviser Sriram Krishnan posted on the social media platform X.

Krishnan has played a central role in the Trump administration's push to develop a national framework for regulating AI developments.

His exit arrives as the president explores the possibility of the US government taking stakes in AI companies.

"There's something very interesting about it, where it almost becomes a partnership with the American public," Trump told reporters aboard Air Force One on Friday, noting plans to meet with AI executives as soon as next week.

Embrace of AI Complicated by Security Concerns of Trump Admin

Trump's support for AI has at times been tempered by security concerns about the technology inside his own administration.

Fears over AI's unknowns in national security led to a months-long standoff between the Trump administration and AI firm Anthropic.

The Pentagon blacklisted Anthropic earlier this year after the tech company declined to allow the US military to use its models for domestic surveillance and fully autonomous weapons systems.

Following a White House meeting with the CEO of Anthropic, which is preparing to go public, tensions have appeared to ease.

The White House, in a Tuesday executive order, directed federal agencies to ask leading AI developers to voluntarily submit their most capable models for government cybersecurity tests before releasing them to the public.

Some populists in the president's circle caution that AI carries political risks, as plans to build data centers to power these companies have sparked strong opposition.

In his State of the Union speech in February, Trump said he urged big tech companies to construct their own power plants. Tech CEOs later committed to addressing new electricity generation and efficiency measures.
