The Internal Revenue Service has placed two employees on administrative leave in connection with a 2010 conference in Anaheim, California, which cost millions of taxpayer dollars.

The employees were not identified in a Wednesday statement from IRS Acting Commissioner Danny Werfel, nor were the exact circumstances of their alleged wrongdoing detailed.

The incident involved a party inside a private suite at a hotel in Anaheim, the statement said. Food was allegedly provided free of charge, a violation of standards.

Pending further review, the IRS has started the process of removing the employees.
