WASHINGTON, D.C. -- Rep. Cynthia McKinney admits that she broke government rules by spending money to fly a celebrity to Atlanta.

Channel 2 Action News has uncovered documents showing McKinney, D-Ga., spent about $1,000 of taxpayer's money to fly singer Isaac Hayes to Georgia to help dedicate a new office in Atlanta.

The money came from a fund members of Congress are supposed to use for office supplies.

Using the money to pay for Hayes' airline ticket and hotel expenses is a violation of strict congressional rules. Those rules state that taxpayer money can only be used for "travel by Members, Members' employees and vendors. A vendor is an employee of a private company that provides maintenance and support for equipment and software..."

Watchdog groups call taxpayer-funded celebrity travel a blatant waste of taxpayer money.

McKinney staffers say they will reimburse the congressional fund for the cost of Hayes' flight and hotel room.
