About 77,000 federal employees across the United States — including attorneys, air traffic controllers, medical personnel and information technology specialists—had higher salaries in 2009 than the governors of the states they worked in, a new report shows.

The data from the Congressional Research Service could add fuel to a debate on Capitol Hill about whether the salaries and benefits of federal workers are too high compared with their counterparts in the private sector. The report was first reported by the Washington Times.

The information was requested by Sen. Tom Coburn (R-Okla.), who has argued that federal workers should be paid less as the government seeks ways to rein in its growing deficit.

The research service reviewed civilian salary data in the executive branch provided by the Office of Personnel Management for 2009, the last year available. Of the 77,057 federal workers who earn more than the governors of their states, 18,351 were physicians, the highest percentage. Air-traffic controllers came in second at 5,170. The government has about 2 million employees.

Colorado topped the list with 10,875 people making more than Gov. Bill Ritter, whose pay was $90,000. In Maryland, 7,283 civil servants made more than Gov. Martin O’Malley, who was paid $150,000. Virginia had 606 federal workers who took home more than Gov. Tim Kaine, whose salary was $175,000.

“Federal employees deserve to be paid adequately, and no one would argue against paying skilled engineers or top-notch doctors and nurses to care for wounded soldiers and veterans,” Becky Bernhardt, a spokeswoman for Coburn, said in a statement. “It seems to defy explanation, however, why recreation planners , an interior designer and many other public servants are receiving higher salaries than state governors  when our nation is $14 trillion in debt and many taxpayers are struggling to pay their mortgage and make ends meet.”

The report does not provide federal workers’ individual salaries. It does not account for labor and living costs among states, which can affect federal pay, nor does it take into account education levels and years of experience. Hard-to-fill jobs that might draw higher salaries in some states than in others also are not distinguished.

An official with the largest union of federal workers, the American Federal of Government Employees, said politicians would be better off scrutinizing the salaries of federal contractors.

“So the government’s paying $700,000 and more for contractor salaries, and Senator Coburn worries about the pay of physicians who care for wounded soldiers?” Beth Moten, the union’s legislative and political director, said in a statement. She noted that defense contractors can be reimbursed up to $693,000 from the government toward the salaries of their top five executives.

“If those governors want to make more money, they should either become contractors or try applying to medical school,” Moten said.
