Here’s a copy and paste from the announcement with bolding added by me - it seems to me that TSA PreCheck should be having normal operations:
TSA
As the Transportation Security Administration enters emergency operating status, resources are being consolidated to prioritize essential security operations and focus personnel on detecting and countering threats.
- Effective at 6:00 a.m. on February 22, nonessential privileges and courtesies provided by TSA will be suspended. All courtesy escorts, including for members of Congress, will cease. These escorts put increased strain on our officers, who must be allowed to prioritize their critical work of screening passengers.
- At this time, TSA PreCheck remains operational with no change for the traveling public. As staffing constraints arise, TSA will evaluate on a case by case basis and adjust operations accordingly. Courtesy escorts, such as those for Members of Congress, have been suspended to allow officers to focus on the mission of securing America’s skies.
Until funding is restored, all travelers should expect a process that does not sacrifice security.
