Brennan: 20% Terrorist Recidivism Rate 'Isn't Bad'

President Obama's national security adviser, Gen. Jim Jones, defended his deputy on Sunday, saying he's glad John Brennan is on his side and he agrees with his assessment that the United States can't stop 100 percent of captured terrorists from returning to the field.

Brennan, the president's top counterterrorism adviser, on Saturday compared the U.S. criminal recidivism rate of 50 percent to the one in five terrorists who are released to other nations and return to the battlefield.

"Twenty percent isn't that bad," Brennan said.
