The U.S. Government won't explain, but a 9 News Now investigation has found $30 million in unreported bonuses for fiscal year 2011 - making the already troubled General Services Administration's total bonus pool nearly $44 million.

"Just outrageous," said U.S. Rep John Mica, Chairman of the House Transportation and Infrastructure Committee. "All put on the taxpayers tab. There are very serious problems for GSA. "

GSA does not respond to interview requests

GSA officials did not respond to interview requests, but issued a statement saying Acting Administrator Dan Tangherlini "is reviewing all bonuses and the entire performance award system."

Mica shares GSA oversight responsibility with Congressman Jeff Denham.

"We've known that there is a culture of waste, fraud and abuse," said U.S. Rep Jeff Denham (R-Ca.), Chairman of the House Subcommitte on Oversight.  "This proves that this is a systemic problem that is rooted deeply within this organization."

Mica plans to bring out the bonus records uncovered by 9 Wants to Know during a congressional hearing into GSA mismanagement scheduled to begin Wednesday morning.

WUSA9 investigation reviewed over 13,000 payroll records

The $44 million in bonuses should have been released in May, when the Office of Personnel Management released GSA payroll and bonus information, but until WUSA9 sorted through the newly obtained 13,000 GSA pay records, the troubled agency had reported less than a third of its bonus pay.
