WASHINGTON — A congressional committee is investigating allegations that the agency in charge of airport security retaliated against employees who reported security lapses and awarded bonuses to supervisors who ignored their warnings.

The agency, the Transportation Security Administration, has until March 4 to provide the House Oversight Committee with documents detailing how it awards bonuses to top agency officials.

The investigation comes after Andrew Rhoades, an assistant federal security director at Minneapolis-St. Paul International Airport, sent documents to the committee that he said indicated that the top supervisors who ignored warnings about security lapses were awarded bonuses.

One top official in charge of security for the agency received more than $70,000 in bonuses in a three-year period despite a leaked audit that showed screeners failed to detect investigators with fake weapons and bombs going through security lines. The audit showed that screeners failed to detect the weapons 95 percent of the time.
