The fight over whether workers at a Volkswagen plant in Tennessee can unionize is moving to Washington.
Two House Democrats said Wednesday they will investigate whether Republicans in that state may have violated "or otherwise run afoul" of any federal laws ahead of a February vote in which workers narrowly opted against joining the United Auto Workers.
Congressmen George Miller of California and John Tierney of Massachusetts say they want to know if any Tennessee Republicans attached any inappropriate strings to the state's $300 million incentive package to get VW to expand the Chattanooga plant.
The union claims the election was tainted by Republicans including U.S. Sen. Bob Corker, R-Tenn.
Corker and others have denied doing anything inappropriate.
A hearing on the UAW's complaint is set for Monday in Chattanooga.
