The Kentucky senator questioned Homeland Security Secretary Jeh Johnson on the bulk collection of phone records, and argued that consumers’ desire for encryption is a response to government surveillance.

“The real culprit is government,” Paul said during a Senate Homeland Security Committee hearing.“You’ve been so overzealous vacuuming up our records without a legitimate warrant … [Encryption] is a response to a government that didn’t have a real sense of decency toward privacy.”

Paul also criticized the government for surveillance during the civil rights era, which he described as a cautionary tale.

"Look at the time the government wasn’t so good. The FBI director recently pointed back and talked about the times that Martin Luther King was spied upon. That's why we want these procedural protections," he said.



Johnson, who has been making the rounds in tech circles arguing against full encryption, declined to weigh in on bulk data collection but urged Congress to act.



“I’m in favor of a balanced solution to the [encryption] problem,” he said, adding that encrypting records makes it harder to conduct criminal investigations. “I think it’s something we need to address."



Johnson spoke to a major cybersecurity conference in San Francisco last week, where his stance on encryption was ridiculed by tech experts. “I wasn’t real popular for doing that,” he said of his speech.



Paul replied that bulk records collection is “not a balanced approach,” and said agencies must be made to seek warrants as part of the process.

As the GOP field’s main libertarian, Paul has aggressively courted Silicon Valley backers.
