National Security Agency whistleblower Edward Snowden took to Reddit Thursday, once again answering questions about surveillance reform, Kentucky Senator Rand Paul's 10-hour filibuster, and whether or not he misses pizza in Russia.

Snowden answered numerous questions during a Reddit AUA, or "Ask Us Anything," which he participated in alongside American Civil Liberties Union Deputy Legal Director Jameel Jaffer. Snowden was asked how he felt seeing Republican Senator Rand Paul stage a filibuster for almost half a day in an attempt to block a clean renewal of the Patriot Act, which the NSA has used to justify collecting Americans' telephone data in bulk.

"It represents a sea change from a few years ago, when intrusive new surveillance laws were passed without any kind of meaningful opposition or debate," he responded. "Whatever you think about Rand Paul or his politics, it's important to remember that when he took the floor to say 'No' to any length of reauthorization of the Patriot Act, he was speaking for the majority of Americans – more than 60% of whom want to see this kind of mass surveillance reformed or ended."

The House of Representatives has already passed legislation, called the USA Freedom Act, which would reform the way the NSA gains access to data. It would still allow intelligence officials to view metadata – the time that a call was made, to whom it was made, but not the actual content – but they would be required to submit keywords to phone companies in order to do so.

Some have hailed this development as an important step towards reforming NSA surveillance, while others claim the keywords can be so broad that bulk collection would still happen. Even if it passes, however, the language generally concerns one portion of the Patriot Act, called Section 215.
