White House AI adviser Krishnan to leave role

White House artificial intelligence policy adviser Sriram Krishnan said he will leave his post at the end of June, ending a brief but influential run in the Trump administration. Krishnan said on X that serving in the role was "the privilege of a lifetime" and did not give a reason for his departure. He has helped shape the administration’s approach to AI policy, including efforts to build a national framework for regulating advanced systems. His exit comes as Washington has increased scrutiny of frontier AI tools, with security concerns rising over how powerful models could be tested and controlled before public release. The White House recently issued an executive order asking major AI developers to voluntarily submit their most capable systems for cybersecurity testing.
