The claim is comprehensively confirmed by multiple independent, high-authority sources. The official Senate Banking Committee PDF (banking.senate.gov) is itself the 309-page draft in question, directly verifying the page count and the committee's authorship. CoinDesk's reporting confirms the public release ahead of Thursday's markup and notes the text had previously circulated privately within the crypto industry. The X posts by @EleanorTerrett and @Cointelegraph, both published on May 12, 2026, independently corroborate the 309-page figure, the Senate Banking Committee as the releasing body, and the Thursday markup timeline. All specific claims - the 309-page length, the Senate Banking Committee as the releasing body, the digital asset market-structure subject matter, the pre-markup timing, and the prior private circulation - are confirmed with no conflicting evidence found.
