Former U.S. congressman Ron Paul (R) shakes hands on Parliament Hill in Ottawa March 7, 2013.
Sen. Rand Paul, R-Ky. is questioned by reporters in an elevator as he leaves a GOP policy meeting on Capitol Hill in Washington, Thursday, March 7, 2013. Call it Rand's Stand: a nearly 13-hour filibuster on the Senate floor that is thrusting a tea party hero back into the national spotlight. Paul's Wednesday night filibuster of President Barack Obama's pick for CIA director drew comparisons to the movie "Mr. Smith Goes to Washington." Paul, the son of former Congressman and presidential candidate Ron Paul, repeatedly demanded assurances that the administration would not use drones in the United States to kill terrorism suspects who are U.S. citizens. He got that assurance on Thursday. Paul is a freshman senator who challenged the Republican party's establishment to win his seat in 2010 and now commands attention as a defender of limited government.
