Former President George W. Bush defended PRISM, the Internet spying program he helped enact, while taking whistleblower Edward Snowden to task.
"I put that program in place to protect the country. One of the certainties was that civil liberties were guaranteed," Bush told CNN in an interview airing Monday.
"I think there needs to be a balance, and as the president explained, there is."
PRISM began under the Bush administration but stayed secret until The Washington Post and The Guardian (UK) revealed its existence last month.
