Here is a political story that resists easy categorization, which is precisely why it deserves your attention. Sen. Mike Lee of Utah — one of the most reliably conservative voices in the Senate — has co-authored a surveillance reform bill with Sen. Dick Durbin of Illinois, a progressive who last agreed with Lee on roughly nothing. On the other side: the Trump administration, the intelligence community, and the wing of the Republican Party that has never met a national security power it didn't want to expand. The subject is Section 702 of the Foreign Intelligence Surveillance Act, and the debate it's igniting goes to the core of what it means to believe in limited government — not just when it's convenient, but when it's hard.
What Section 702 Actually Does
Section 702 authorizes the NSA to collect the communications of foreign targets located outside the United States — without a warrant, as foreign intelligence gathering has historically required none. In practice, this is enormously valuable. Counterterrorism officials have credited the program with disrupting genuine plots. Nobody serious proposes eliminating it [1]. The problem is what happens on the edges. When foreign targets communicate with Americans, those Americans' messages get swept up too. This is called "incidental collection," and the law permits it. What happens next is where the abuse enters the picture: intelligence agencies, including the FBI, have conducted warrantless searches of that database using American citizens' names, phone numbers, and email addresses. Not to catch foreign spies. To look up journalists. Political campaign donors. Members of Congress. People the government found interesting.
