The promise was to call on the Department of Justice to use every available tool against oil-industry collusion and price fixing. Evidence shows Senator Tammy Duckworth joined a May 30, 2024 Senate letter to Attorney General Merrick Garland and Antitrust chief Jonathan Kanter making that exact request, and her name appears among the signers on the letter itself. Because this action occurred during her current Class III Senate term running from January 3, 2023 to January 3, 2029, the promise counts as delivered in the same term. The claim is about making the call on DOJ, not about DOJ ultimately securing prosecutions.

Duckworth fulfilled the oversight promise by joining a May 31, 2024 Senate letter to Attorney General Merrick Garland and Assistant Attorney General Jonathan Kanter explicitly calling on DOJ to use every tool available to prevent and prosecute oil-industry collusion and price fixing. The promised action was to call on DOJ, not to secure DOJ prosecution outcomes, so the co-signed letter satisfies the claim during her current Senate term.

Senator Duckworth fulfilled her campaign promise by joining other senators in formally calling on the Department of Justice to take action against collusion and price fixing in the oil industry. Co-signing a public and official letter urging DOJ to use every tool at its disposal is a direct and substantial effort matching the commitment in the promise.
