The legal authority behind one of the US government's most important intelligence gathering tools has expired. Section 702 of the Foreign Intelligence Surveillance Act, known as FISA 702, lapsed after Congress failed to renew it, leaving the program without its statutory footing.
The lapse came after a bipartisan coalition tanked an emergency extension that had been put forward to keep the authority alive. The split was sharp: some lawmakers argued the measure deserved to be voted down, while others described allowing the program to go dark as completely irresponsible.
The timing has heightened the unease. Officials warned of what they called unprecedented vulnerabilities this summer, pointing in particular to the start of the World Cup. Lawmakers voiced fear over the gap, with one saying he prays that nothing happens in the country where an American is killed.
At its core, Section 702 allows intelligence agencies to siphon the calls, emails and text messages of foreign intelligence targets. It has been described as one of the government's foremost weapons for detecting and foiling terrorism, which is why its expiration has set off alarm in national security circles.
There is, however, a cushion. According to officials, a court ruling means the government can still track suspect communications for up to a year despite the lapse in the law. That has led some to argue the situation is not as dire as the loudest warnings suggest, at least in the short term.
The bigger uncertainty lies with the companies that actually carry the data. It is unclear whether telecommunications providers will continue handing communications to the government without a congressional safeguard in place, an ambiguity that officials themselves describe as a gray area still to be worked through.
There is also an expectation that the carriers will grow increasingly uncomfortable taking part in 702 collection without statutory protection covering their role. With the authority now expired and no replacement agreed, the question of how surveillance continues, and on what legal basis, remains unresolved.
