Thomas Drake: The Edward Snowden revelations broke when I was serving as chairman of the House Judiciary Committee. I experienced firsthand the reality that secrecy in the service of national security is sometimes necessary in our nation’s surveillance programs. Unfortunately, I also saw that claims of secrecy can be used by our intelligence agencies to spy on Americans without warrants and in violation of the Constitution.

"the government argues that upstream surveillance is too secret for Wikimedia’s case to go forward, invoking the “state secrets privilege” and claiming that any use of sensitive evidence to defend the case could hurt national security. In a split decision, a federal appeals court threw out the case citing state secrets."
