Markwayne Mullin made the claim in a briefing on 13 November 2026, during the nationwide FAA ground stop, as reported by dnyuz.com and CBS News.

Our verdict

True

The claim is accurate. Markwayne Mullin said the nationwide FAA ground stop was caused by a telecommunications outage, and official statements and news reports from that day back him up.

What we found

We found strong agreement across several independent outlets. CBS News reported that Markwayne Mullin said the FAA ground stop was caused by a telecommunications outage, and dnyuz.com ran the same statement under the headline "Mullin Says Nationwide Ground Stop Is a Telecommunication Outage". ABC News and AVweb both confirmed that the FAA ordered a nationwide ground stop on 13 November 2026, and Aerotime reported it was due to a communications outage. The cause was described in slightly different words elsewhere — CNN and The New York Times said Mullin pointed to technology upgrades overwhelming the system, while NHPR reported the FAA and the Transportation Secretary blamed outdated, overloaded communications technology. All of these describe a telecommunications or communications failure, so they support the claim rather than contradict it.
