Although The Washington D.C. based group FreedomWorks was created in the mid-aughts, most people outside the Beltway didn't hear of it until the Tea Party movement exploded in 2009.

It's been a leading organization in growing the movement — perhaps the leading organization.

It's also been used as a bogeyman by critics who claim that the Tea Party isn't grassroots, citing the funding it's received from FreedomWorks, which is tied closely to its founder — corporate lobbyist and former Texas Congressman, Dick Armey.

This Saturday, FreedomWorks' members will hold an opening for their new Tampa campaign office at 1311 West Shore Blvd., Suite 101, from 10 a.m.-noon.
