Ted Cruz is speaking on the Senate floor now, and has vowed to speak until he can no longer speak. While not technically a filibuster, it could have the same impact on the political discussion. See and listen to him live here:
Please support Ted and his fellow conservatives by emailing or calling your Senator now and demanding that they listen to Cruz carefully–and to understand that Cruz speaks for tens of millions of Americans who are sick of the establishment GOP and its progressive ways! Demand that they support the defunding of Obamacare!
