“The House got it done last night. Now, it’s the Senate’s turn.” “I’m encouraging all of our members here in the United States Senate to support this really commonsense legislation that has come forward from the House.”
Support legislation to allow year-round E15 fuel sales nationwide.
Occurrences
I remain focused on securing ... permanent, year-round access to E15 so consumers have cheaper options at the pump and farmers have stronger markets for the crops they grow.
Evidence
Ernst's office said she renewed support for the Nationwide Consumer and Fuel Retailer Choice Act and said Congress should permanently enact nationwide E15.
Congress.gov lists Sen. Joni Ernst as an original cosponsor of S.593 on February 13, 2025; the bill was referred to Senate Environment and Public Works and remained introduced.
The House passed H.R.1346, the Nationwide Consumer and Fuel Retailer Choice Act, by a 218-203 vote on May 13, 2026.
CRS explains that temporary emergency fuel waivers are limited to 20 days, permanent year-round sales were proposed in S.593 and H.R.1346, and a 2024 provision was not enacted.
EPA issued a temporary emergency waiver allowing nationwide E15 sales beginning May 1, 2026, initially through May 20, 2026.
The D.C. Circuit held that EPA exceeded its authority and vacated the portion of the 2019 E15 Rule granting a fuel volatility waiver to E15.
Congress.gov lists Joni Ernst as a cosponsor of S.593, but the bill's latest action is still 'Read twice and referred' to Senate Environment and Public Works, with no Senate passage recorded.
The House passed H.R.1346 on May 13, 2026, by a 218-203 vote, but that was only one chamber; Senate passage and presidential approval were still outstanding.
On June 9, 2026, EPA extended the waiver allowing production and distribution of a single national gasoline pool with 9 to 15 percent ethanol at a common Reid Vapor Pressure standard of 10 psi. The page says both waivers share a 20 day effective window from June 10, 2026, until June 29, 2026.
Congress.gov lists Sen. Joni Ernst as a cosponsor of S.593, and the bill's latest action remains 'Read twice and referred to the Committee on Environment and Public Works.' The page also says the bill has the status Introduced.
Assessments
The claim is framed as support for legislation, not as successfully enacting nationwide year-round E15 into law. In her current Senate term, Joni Ernst publicly backed permanent year-round E15 and served as an original cosponsor of S.593 in February 2025, which is direct legislative support. The broader policy had not yet been enacted nationwide, but for this promise wording, her sponsorship and advocacy satisfy the commitment.
Joni Ernst did materially support the push for year-round E15 by becoming an original cosponsor of S.593 and publicly advocating permanent nationwide E15, but the legislation still had not passed the Senate or been enacted into law. The policy outcome was therefore not delivered, even though she made a serious legislative effort.
Ernst did support the promised legislation by serving as an original cosponsor of S.593 and publicly advocating permanent nationwide year-round E15 access. However, the promised policy outcome has not been enacted: S.593 remained pending in the Senate, H.R.1346 only passed the House and still required Senate passage and presidential signature, and EPA's 2026 waiver was temporary rather than permanent legislation. This is a serious legislative attempt without completed delivery.
