Washington ( CNN ) -- Sen. Mark Udall accused the CIA of `` lying '' about the effectiveness of torture , called for the resignation of its director and blasted President Barack Obama 's handling of the spy agency on the Senate floor Wednesday . In a 48-minute speech , the Colorado Democrat called on Obama to `` purge his administration '' of CIA officials , including Director John Brennan , involved in the interrogation techniques detailed in a new Senate Intelligence Committee report . He also revealed what he called the `` key findings and conclusions '' of an internal CIA review commissioned by former director Leon Panetta -- which the Obama administration has not publicly released . `` Director Brennan and the CIA today are continuing to willfully provide inaccurate information and misrepresent the efficacy of torture , '' Udall said . `` In other words : The CIA is lying . '' White House Press Secretary Josh Earnest defended Brennan on Wednesday , telling reporters that he has done an `` exemplary job '' and that Obama is `` pleased to rely on his advice . '' Udall 's comments came the day after Senate Intelligence Committee Chairwoman Dianne Feinstein ( D-Calif. ) released an explosive report detailing the rough techniques the CIA used to interrogate detainees under President George W. Bush . The report suggests those techniques -- including mock executions , sleep deprivation , beating detainees , feeding them rectally and threatening the lives of their families -- produced faulty intelligence . It also said the CIA misled Congress and the White House . But Brennan pushed back , acknowledging in a statement that the CIA made `` mistakes '' but saying those techniques `` did produce intelligence that helped thwart attack plans , capture terrorists , and save lives . The intelligence gained from the program was critical to our understanding of al-Qa'ida and continues to inform our counterterrorism efforts to this day . '' Udall -- who lost his re-election bid in November and is leaving office in just weeks -- said he was frustrated with those comments Wednesday , and repeated his previous call for Brennan 's resignation . He also accused Obama of failing to live up to his pledges during the 2008 campaign to be more transparent about the use of torture . And he said the CIA 's internal Panetta review 's findings reveal that the White House is misleading the public . `` One would think this administration is leading the effort to right the wrongs of the past and ensure the American people learn the truth about the CIA 's torture program , '' Udall said . `` Not so . It 's been nearly a six-year struggle in a Democratic administration to get this study out . For a while I worried that this administration would succeed in keeping this study entirely under wraps . `` While the study clearly shows that the CIA detention and interrogation program itself was deeply flawed , the deeper , more endemic problem lies in the CIA , assisted by a White House that continues to try to cover up the truth .
