"Senator Rubio is asking for American technology companies to ‘cooperate with authorities,’ so I believe he will have no objection to authorities being given access to his electronic correspondence and metadata."

"Maybe after his 2016 strategy documents are accidentally caught up in a government data grab, he’ll rethink the use of mass surveillance," Polis continued, a reference to Rubio's potential presidential bid.

In his op-ed, published by Fox News, Rubio called for "a permanent extension of the counterterrorism tools our intelligence community relies on."

"The U.S. government should implore American technology companies to cooperate with authorities so that we can better track terrorist activity and monitor terrorist communications as we face the increasing challenge of homegrown terrorists radicalized by little more than what they see on the Internet," he wrote.

Former contractor Edward Snowden's 2013 leaks that revealed the National Security Agency's mass surveillance programs sparked a debate over privacy concerns and national security.

The NSA's critics have vowed to rein in the agency's practices, but a reform bill failed to pass Congress last year.
