HuffPost's live-updates article tracks the FAA's nationwide ground stop, which halted flights for roughly four hours Friday, leaving thousands canceled or delayed, with Transportation Secretary Sean Duffy pointing to possible error by contractor L3Harris, saying officials do not believe it was a cyberattack, and urging Congress to fund air traffic control upgrades. The blog also covers a Workday software outage and President Donald Trump's attacks on Governor Gavin Newsom's decision to commute the sentences of more than 500 California death row inmates.
