WASHINGTON - An elite group of federal employees is set to receive cash bonuses, despite this year's automatic budget cuts, according to a report that a Senate subcommittee issued Friday.

The report revealed that members of the government's highly paid Senior Executive Service - who make up less than 1 percent of the federal workforce - had received more than $340 million in bonuses from 2008 through 2011. The bonuses came on top of annual salaries that ranged from $119,000 to $179,000.

In a process known as sequestration, $85 billion in across-the-board federal spending cuts took effect March 1, forcing the government to slash services and furlough workers. A month later, the Obama administration froze bonuses for the vast majority of federal workers.

But by law, agencies still must pay bonuses to Senior Executive Service employees who meet certain performance criteria, the report said.

Sen. Claire McCaskill (D., Mo.) introduced a bill Friday that would eliminate bonuses for members of the Senior Executive Service during sequestration. McCaskill leads the Senate Subcommittee on Financial and Contracting Oversight, which produced the report.

"The idea that some of the highest-paid federal government employees could be getting bonuses while others are being furloughed is outrageous," McCaskill said in a statement. "This legislation will ensure that doesn't happen."

Created by the Civil Service Reform Act of 1978, the Senior Executive Service is made up of leaders who serve in key positions just below top presidential appointees, according to the U.S. Office of Personnel Management website. They oversee the day-to-day activities of about 75 federal agencies.

Friday's report found that the federal government had handed out more than 6,300 cash awards to members of the Senior Executive Service in 2011, for a total of $78 million. Most Senior Executive Service employees - 81 percent - received bonuses that year, the report said.
