Democrats pledge to investigate FAA ground stop; Johnson says no probe needed

Following a nationwide Federal Aviation Administration ground stop on November 13, 2026, caused by a router maintenance error that disrupted over 15,000 flights, House Democrats vowed to investigate the Trump administration when taking the majority in January 2027. Administration officials attributed the breakdown to outdated infrastructure overloaded during a fiber-optic upgrade by contractor L3Harris. While Speaker Mike Johnson rejected calls for a congressional probe in favor of funding upgrades, Transportation Secretary Sean Duffy requested $50 billion for system modernizations.
