(CNN) - Former Vice President Dick Cheney is again taking aim at President Obama, issuing a statement Monday suggesting the administration's decision to name a prosecutor to investigate CIA interrogations under President Bush fuels "doubts about this administration's ability to be responsible for our nation's security."
"The people involved deserve our gratitude," Cheney said in the statement. "They do not deserve to be the targets of political investigations or prosecutions."
The former vice president also said documents released Monday prove enhanced interrogation techniques yielded valuable information that "provided the bulk of intelligence we gained about al Qaeda."
"This intelligence saved lives and prevented terrorist attacks," Cheney said. "These detainees also, according to the documents, played a role in nearly every capture of al Qaeda members and associates since 2002."
"The activities of the CIA in carrying out the policies of the Bush Administration were directly responsible for defeating all efforts by al Qaeda to launch further mass casualty attacks against the United States," he added.

Late Monday, the government released declassified CIA documents originally requested last May by Cheney. The former vice president had argued they would show enhanced interrogation techniques saved lives.
While analysis in the documents says information from detainee interrogations "helped thwart a number of al-Qaida plots" and "arrests...disrupted attack plans in progress," it remains unclear from the heavily redacted documents whether that information was obtained through the enhanced interrogation techniques Cheney defends.
The documents' release came the same day Attorney General Eric Holder asked federal prosecutor John Durham to examine whether CIA interrogations of suspected terrorists were illegal after the release of a 2004 CIA inspector general's report into further questionable interrogation techniques.
