Fischbach fulfilled the promise as framed because it was to support the Diesel Engine Flexibility Act, not necessarily to secure final enactment. She was an original cosponsor/introducing member of H.R. 9618 in the 119th Congress, and the bill advanced from the Environment Subcommittee to the full House Energy and Commerce Committee by voice vote during her current federal term. The bill had not become law as of August 17, 2026, so the underlying policy outcome was not enacted, but her promised act of support was delivered.
