Senator Rand Paul seeks answers about Obama's elusive kill-list. (VIDEO)

Sen. Rand Paul (R-Kentucky) has some questions for John Brennan, and Esquire writer-at-large Tom Junod says that the lawmaker has an obligation to answer. Brennan has been picked by US President Barack Obama to serve as the next head of the CIA, but Sen. Paul says he will but a hold on that nomination until he hears the truth about the covert drone program that Brennan oversaw as a counterterrorism expert for the administration. Sen. Paul could very well halt the nomination, but will Americans hear the truth about the nation's foreign drone wars? RT's Liz Wahl discusses the matter with Mr. Junod, who weighs in on the secretive use of drones to execute insurgents, terror suspects and even US citizens overseas.
