For the first time in nearly two decades, Congress has let a major federal surveillance authority expire without reauthorization, leaving open questions about whether certain U.S. intelligence collection programs can continue to operate legally — a development with implications for national security operations that touch Montana's military installations, including Fort Harrison.

Lawmakers have repeatedly extended the authority in question, sometimes in multi-year packages and sometimes in short-term patches, but missed the most recent deadline amid a broader climate of distrust over how the Trump administration has been managing national security decisions. That distrust, cutting across party lines in some cases, proved enough to stall the reauthorization process past the expiration date.

The lapsed authority covers the collection of certain foreign communications, and its absence creates legal uncertainty for intelligence agencies that rely on it. Whether those agencies can continue operations during a lapse, and for how long, is a question that has historically been resolved through emergency measures or rapid congressional action — though no such fix was immediately in place at the time of the expiration.

For Montanans, the practical stakes are somewhat removed from daily life, but Fort Harrison and Montana's National Guard installations operate within a national security framework that depends on functioning intelligence-sharing authorities. The lapse is expected to generate pressure on Congress to act quickly, though the political dynamics that caused the deadline to be missed have not visibly resolved.
