Details

Role

Harmeet Dhillon serves as Assistant Attorney General (AAG) of the U.S. Department of Justice. In this capacity she has been the public face of DOJ's enforcement actions challenging state-level AI regulation.

The SB24-205 Action (April 25, 2026)

On April 25, 2026, Dhillon tweeted: "BREAKING: Hours after the @TheJusticeDept filed suit today, Colorado has agreed to delay enforcement of SB24-205 against ALL AI companies until later this year to give the state legislature time to repeal this unconstitutional law."

Key facts about the action: - The DOJ filed suit challenging Colorado SB24-205's constitutionality. - Colorado agreed to delay enforcement broadly — covering all AI companies, not just the DOJ plaintiffs. - The stated goal was to give Colorado's legislature time to repeal the law entirely. - Dhillon described it as "A good day's work, for a Friday!"

The tweet received significant engagement: 5,106 likes, 1,149 retweets, and 225 replies.

Significance

Dhillon's action represents the first reported DOJ lawsuit against a state AI regulation law. The speed of Colorado's capitulation (within hours, covering all companies) suggests the DOJ's constitutional argument was strong enough to make defense impractical. This establishes a clear executive branch posture: the federal government will actively challenge state AI laws on constitutional grounds.
