Here come the goons.

Workers Voice, the super PAC of the AFL-CIO, is supporting Senate Majority Leader Harry Reid in the fight over Mitt Romney’s tax returns.

The super PAC announced plans on Monday to ramp up efforts calling on the presumptive Republican presidential nominee to release more tax returns. The largest union-affiliated super PAC, Workers Voice launched a petition where anyone can sign and back up the recent charge led by Reid. The group also plans to add the tax return issue to its protests outside of Romney campaign events.

Last week, Reid ignited a firestorm when he told The Huffington Post that Romney didn’t pay taxes for a period of 10 years. Since then the Senate Majority Leader has stood by his claims, which he says are built on information from an anonymous Bain Capital investor. Romney responded by denying the allegations and telling Reid to “put up or shut up.”
