(RT LIVE http://rt.com/on-air)President Obama's choice to become the next chief of the CIA went through a tough confirmation hearing at the US Senate. But it wasn't the lawmakers who put John Brennan under the spotlight over his role in the controversial US drone program. The session was interrupted several times by protesters who put up signs with slogans such as 'Stop CIA Murder'. They were addressing the issue of US drone use for targeted strikes against suspected terrorists. John Brennan defended the program which he helped develop, saying it is "ethical and just" and claiming the strikes are carefully vetted. However, human rights groups claim the program has in fact led to a large number of civilian deaths. So did US lawmakers hold Brennan accountable for his counter terrorism policies? RT's Gayane Chichakyan has the details.
