Bitcoin goes before the Senate again Tuesday after having been given a tentative thumbs up by government agencies during a Senate Homeland Security hearing on Monday. The Banking Committee hearing Tuesday is a littler dryer — less about drugs and murder for hire for Bitcoin, and more about financial and banking issues around virtual currencies. During his opening remarks, hearing chair Senator Mark Warner said that he’s been “following Bitcoin for months” but is only now “wrapping his head around it.” He then remarked offhandedly that the Federal Election Committee recently approved Bitcoin for political donations. But he’s incorrect.
