Senate Judiciary Chair Chuck Grassley is trying to pass a bill before the midterms that would protect whistleblowers who disclose information about the risks involved in artificial intelligence development, according to two people granted anonymity to disclose nonpublic information.

The Iowa Republican is seeking to move it through unanimous consent — a way to expedite passage on the Senate floor that hinges on an agreement from all 100 senators to let the measure through.

Only one senator has to object in order to doom the effort. Grassley is in the process of privately checking with colleagues to see if someone will register opposition, according to the two people with knowledge of his efforts. He likely has until the end of this week to seal the deal, as senators are eager to begin their lengthy recess to campaign ahead of the November elections.

Even if someone indicates privately they oppose the bill, Grassley may go to the Senate floor and try to pass the bill anyways, one of the people said — a way to force a colleague to go on the record publicly blocking the measure and defend their position.

A longtime champion of whistleblower protections, Grassley introduced this specific legislation in May 2025. Original cosponsors included Republican Sens. Marsha Blackburn of Tennessee and Josh Hawley of Missouri, and Democratic Sens. Chris Coons of Delaware, Amy Klobuchar of Minnesota and Brian Schatz of Hawaii. Senate Minority Leader Chuck Schumer and Sen. Kirsten Gillibrand of New York, as well as Sen. Richard Blumenthal (D-Conn.), have more recently signed onto the bill.

The push for passage now comes as a flurry of current and former employees of leading AI labs have emerged to share alarm over the rapid pace of AI advancements and its potential for catastrophic consequences if left unchecked.

And while it wouldn’t come close to the kind of AI regulatory framework some lawmakers are clamoring for Congress to enact, it would represent a step toward bringing some accountability to AI development practices that some critics worry lacks necessary transparency.
