From the CNN article...
The federal government will close...
From the FAA's .pdf...
ATC Facilities That Could Be Closed
Please note the difference in verbiage. This "administration's" shills in the media are saying "will close", while the FAA says "Could Be Closed".
You can expect a change to that "Could Be" once this "administration's" toadies figure out they are off-message and not coordinated with their media water-carriers.
