The one everybody covered went to Speaker Mike Johnson. CNBC’s Megan Cassella reported it first. House Democrats want public hearings on the AI security incidents of the past month, and they want the chief executives of the largest AI companies in the witness chair.

Casar chairs the Congressional Progressive Caucus. His letter does not open by blaming the companies.

“Unfortunately, Congress has so far completely failed to respond to the threats posed by AI development,” it says.

Then it names the ask. “The CEOs of the largest AI companies should answer questions under oath, and Americans should have a chance to hear from independent experts on the dangers posed by this technology.”

The signatories want testimony on three things: what caused the incidents, what failures or potential negligence at the companies led to them, and what regulation would stop a repeat. They call the breaches a possible canary in the coal mine.
