(CNN) - Arizona Sen. John McCain warned Thursday if President Obama prosecuted Bush administration officials who authorized harsh interrogation tactics on terrorist suspects, the process could "turn into a witch hunt."
"If you criminalize legal advice, which is basically what they're going to do, then it has a terribly chilling effect on any kind of advice and counsel that the president might receive," McCain said during an interview on CBS's "Early Show."
"To go back on a witch hunt that could last for a year or so frankly is going to be bad for the country," he said.
McCain, who himself experienced torture tactics as a POW in Vietnam, has been a vocal critic of controversial interrogation techniques used by the Bush administration. Earlier this year, the former 2008 Republican presidential nominee applauded President Obama's decision to end the use of waterboarding as a form of examination.
McCain, along with GOP Sen. Lindsey Graham and Independent Sen. Joe Lieberman sent a letter to the president Wednesday strongly urging him not to press charges on previous administration officials who provided legal analysis in regard to detainee interrogation, writing they "do not support the idea of a commission that would focus on the mistakes of the past."
The term – "Enhanced Interrogation" – The joke that isn't a joke
