Rep. Tammy Duckworth lit into an IRS contractor at a Wednesday hearing in the House Oversight and Government Reform Committee, mocking the witness for claiming a veterans disability for an old prep school injury.

As Chairman Darrell Issa, R-Calif., explained in his opening statement, the witness may have used the agency’s contractor selection process, which includes a preference for businesses run by wounded veterans, in a potentially fraudulent way:

“The intention of, without a doubt, that disabled military veterans receive preference flies in the face of a small injury in 1984 while attending the military academy prep school, one so minor that it had no effect on college football participation for years to follow, and that took 27 years to conveniently ask to have this put in as a disability, not because of a true disability or inability to perform a job, but in fact, in order to qualify for a preference statement.”
