sent draft legislation to Congress, proposing changes in the enforcement structure, an end to the prohibition on state and local candidacies linked to federal funding, and other changes. These changes were largely accepted by Congress in the form of the Hatch Act Modernization Act, which became law on January 28, 2013. It modified penalties under the Hatch Act to allow for disciplinary actions in addition to removal for federal employees and clarified the applicability to the District of Columbia of provisions that cover state and local governments. Additionally, it limited the prohibition on state and local employees running for elective office to employees whose salary is paid completely by federal loans or grants. During this same period, the OSC released a report from its Disclosure Unit detailing the complaints of three U.S. Port Mortuary whistleblowers and the subsequent statutorily-required investigation by their agency, the U.S. Air Force. The report, which included numerous accounts of the mishandling of remains of U.S. service members and their families, received considerable media and congressional attention. Subsequently, OSC reported to the U.S. Air Force that three mortuary supervisors had retaliated against the whistleblowers and should be disciplined.

After investigating the whistleblowers' allegations, the Department of Transportation substantiated 89% of the Office of Special Counsel's referrals. In 2012 alone, OSC received cases concerning air traffic controllers sleeping in the control room, using cell phones, improperly overseeing airline inspection/maintenance programs, allowing unauthorized aircraft to fly in U.S. airspace, and allowing risky landing maneuvers at airports. In April 2011, the Office of Special Counsel entered into a three-year "Demonstration Project" with the U.S. Department of Labor to enforce the Uniformed Services Employment and Reemployment Rights Act (USERRA), which, according to the Office of Special Counsel, "prohibits employment discrimination against veterans and members of the National Guard and Reserve and entitles them to reinstatement in their civilian jobs upon their return from military duty." Under the Demonstration Project, the Office of Special Counsel will "receive and investigate certain USERRA complaints involving federal agencies." In September 2012, at the Office of Special Counsel's request, the MSPB granted a stay request for
