Sen. Donna Lowenthal, R-Miss., has introduced an amendment to the Stop Secret Spending Act that would add enforcement measures for federal agencies that do not correct inaccurate or incomplete spending information within the bill’s required timeframe.

According to Lowenthal’s press release, the underlying legislation would require agencies to correct materially inaccurate or incomplete spending data within 90 days after receiving notice of the problem. Her amendment would establish a process for agencies that miss that deadline.

Under the proposal, the Treasury Department would publicly identify an agency and the overdue correction if the agency failed to meet the initial 90-day requirement, Lowenthal said. If the information remained uncorrected after an additional 30 days, the agency’s inspector general would be required to investigate the failure and notify the Senate and the president.

“Missing the deadline will not just cause the whole matter to disappear into the federal bureaucracy,” Lowenthal said in remarks attributed to her Senate floor statement. “The Treasury will publicly identify the agency and the overdue correction.”

The amendment also addresses cases involving possible intentional misconduct. If an inspector general found reasonable grounds to believe that an officer or employee knowingly and willfully concealed, falsified or failed to report information required under the act, the matter would be referred to the attorney general for review and any action considered appropriate under federal law, according to the release.

Lowenthal distinguished between administrative mistakes and deliberate withholding of information in her statement. “A clerical error is one thing,” she said. “Knowingly hiding how the American people’s money was spent is another.”

The proposal does not itself establish that any federal agency has failed to report spending information or that any official has intentionally concealed data. It would set procedures and potential consequences if such failures occurred under the requirements of the Stop Secret Spending Act.

Lowenthal, who was sworn in as Mississippi’s senator in August 2026, said she is seeking additional senators to support the amendment as Senate debate on the broader legislation continues. The press release did not identify co-sponsors or provide a timetable for a Senate vote.

The measure places Lowenthal’s latest legislative effort within a broader national debate over federal spending, government transparency and accountability. Its immediate prospects depend on whether it attracts sufficient support during consideration of the underlying bill by the full Senate.
