The Washington Commanders and team owner Dan Snyder has had a long couple of years. It might be about to get worse. Wednesday evening it was announced that the U.S. Attorney’s office has opened a criminal investigation into the Commanders, citing potential financial crimes.

The inquiry was reportedly precipitated by a letter the House Committee on Oversight and Reform sent to the FTC (Federal Trade Commission). According to ESPN senior writer Don Van Natta Jr., the letter claimed deceptive business practices for more than a decade.

That includes withholding ticket revenue from visiting teams and refundable deposits from fans.
