Both cited PRIMARY sources were fetched and confirm THIS outcome for THIS promise. Hassan's office (hassan.senate.gov) carries the verbatim headline "SIGNED INTO LAW: Senator Hassan's Bipartisan Bill to Crack Down on Fentanyl Trafficking" and states the bill "requires the Commissioner of U.S. Customs and Border Protection (CBP) to update its policies at least once every three years to ensure that its guidance to stop and interdict drugs is up to date," confirming President Biden signed the bipartisan END FENTANYL Act into law with Hassan as an introducer/co-lead. Rick Scott's office (rickscott.senate.gov) confirms the Act was signed into law, that Scott was the primary sponsor, and states verbatim "The END FENTANYL Act was cosponsored by Senators Jacky Rosen, Mike Braun, Maggie Hassan and Mark Kelly," plus the requirement that the CBP Commissioner "review and update the Office of Field Operations' policies and handbooks, as necessary and at least once every three years." Both cited quotes appear as written and are not fabricated. The promise — to keep working across the aisle against substance misuse "including through the END FENTANYL Act requiring CBP to update its drug-interdiction guidance" — was realized: a bipartisan bill Hassan co-introduced/cosponsored was enacted and does mandate updated CBP interdiction guidance. FULL is the correct, conservative rating: Scott is the sponsor of record so this is not CHAMPIONED singular leadership, but Hassan as an original bipartisan cosponsor/co-introducer did materially more than cast a lone vote, so FULL does not overstate the evidence.
