The US House Office of Legislative Counsel (OLC) is struggling under a growing volume of bills drafted using publicly available AI tools such as ChatGPT and Claude, according to Politico. Congressional lawyers reportedly now spend more time correcting these AI-generated drafts than they would take to write bills from scratch, as the tools frequently produce incorrect terminology, faulty citations and other errors that could distort how laws are ultimately interpreted and applied.

Former OLC head Wade Ballou noted that AI often cannot correctly distinguish between similar legal concepts, such as whether funding should be classified as a tax credit, deduction, exclusion or grant, and can wrongly define "state" in ways that exclude DC and tribal nations from federal programmes. There are also concerns that reliance on AI is leaving Congressional staffers less familiar with the substance of their own proposals. In response, the OLC has developed its own tool, the Comparative Print Suite, which flags errors rather than risking hallucinated changes to draft legislation.
