President Donald Trump broke nearly two days of silence on the nationwide FAA ground stop on Sunday, November 15, 2026, calling on Congress to approve the money to rebuild America's air traffic control system "all at once" after a router failure halted every US departure for nearly five hours and left more than 15,000 flights cancelled over the weekend.

Key Points

• Trump made his first direct comments on the FAA ground stop in a November 15 social media post, after nearly two days of silence on the crisis.
• He urged Congress to approve "the desperately needed money for Air Traffic Control," saying the new system "will be the BEST SYSTEM anywhere in the World."
• The ground stop was ordered at 3:45 p.m. ET on Friday, November 13, after a new L3Harris router flooded the FAA's communications network; flights resumed at 8:15 p.m.
• More than 15,000 flights were cancelled from Friday to Sunday, with over 1,600 cancelled and almost 4,200 delayed on Sunday alone, according to FlightAware.
• Transportation Secretary Sean Duffy is asking Congress for $50 billion more, while House Democrats say only $1 billion of the $12.5 billion approved in 2025 has been spent.

What Happened

Trump's message on Sunday was his first direct word on the crisis since the Federal Aviation Administration ordered every departure in the United States to stop on Friday afternoon. "If Congress approves the desperately needed money for Air Traffic Control, we can get it built quickly and efficiently. It will be the BEST SYSTEM anywhere in the World," he wrote. "We have already started the work, but it should be done all at once, not in drips and drabs. Congress must approve."

Until Sunday, the president had taken a back seat while the air travel problems unfolded. His only earlier reference was indirect: on Saturday, November 14, he shared comments attributed to Senator John Kennedy, Republican of Louisiana, saying additional FAA funding should be a "stand alone Bill." Instead, Transportation Secretary Sean Duffy and Homeland Security Secretary Markwayne Mullin led the public response. Trump also used a second post on Sunday to attack former President Joe Biden, alleging he spent FAA money "unwisely."

Background and Context

The ground stop was ordered at 3:45 p.m. ET on Friday, November 13, after a breakdown in the FAA's communications network. A new router at a facility in El Dorado, Arkansas, installed during a copper-to-fiber upgrade, started "flooding other routers in our air traffic control system," Duffy said on November 14. A system replaced roughly three weeks earlier at a facility in Amarillo, Texas, also began causing problems, and L3Harris is now examining both routers.

Thousands of flights were halted, and although departures were cleared to resume at 8:15 p.m. on Friday, the stop created a backlog airlines were still untangling days later. It was the longest nationwide halt since September 11, 2001, and only the third nationwide ground stop in US history. The FAA's network still runs partly on copper wiring installed decades ago.

FAA Ground Stop: Trump's Push for Full Funding

At the centre of Trump's message is money. Duffy warns more incidents will occur without major investment, and he is asking Congress for $50 billion more. Trump echoed that demand, saying the work should be done "all at once, not in drips and drabs".

House Democrats pushed back in a statement on Friday, November 14, saying much of the $12.5 billion approved for FAA improvements in 2025 remains unspent. "Fifteen months later, the administration's obligated $4.3 billion but only spent $1 billion, leaving $8 billion unobligated and $11 billion unspent," Representatives Rick Larsen, Democrat of Washington, and Andre Carson, Democrat of Indiana, said. "Explain to Congress, again, why they need more money?" Duffy said on Fox News on Sunday that the $12.5 billion will be "deployed" by the end of 2028 but was allocated for specific purposes. "I need additional money to do the additional work to keep the air space safe," he said. Also read: Duffy Blames L3Harris Contractor Work and Faulty Router for FAA Ground Stop.

Reactions and Quotes

Duffy struck an optimistic note about the recovery, telling NBC's "Meet the Press" on Sunday that airlines would soon be operating normally. "By the end of the day, end of tomorrow I think we'll be back to normal," he said. His reassurance came as Sunday's cancellations still topped 1,600.

Democrats accused the Trump administration of incompetence and are calling for accountability and oversight to dig into what caused the ground stop. "Our committee, on behalf of the flying public, will hold the administration accountable for what happened to make sure this chaos does not happen again," Larsen and Carson said, vowing oversight hearings. Trump wants a big, fast funding bill and blames his predecessor, while Democrats want answers first about the unspent $12.5 billion.

Why It Matters

The ground stop was more than a bad travel weekend. It was the second time in American history, outside of September 11, that the entire national airspace system was ordered to a halt, and it happened because of a routine equipment upgrade, not an attack or a storm. That is what makes the failure so alarming: if swapping a router can ground the country, the system has almost no margin left. Whether Congress approves $50 billion more, or first demands proof the money already approved is being spent, will decide how fast the upgrade moves.

What Happens Next

Flights were expected to return to normal by the end of Sunday or Monday, according to Duffy, but the political aftershocks will last longer. House Democrats have vowed oversight hearings, and L3Harris is examining the routers from both the El Dorado and Amarillo facilities as investigators ask whether the failure was installer error or a defective part. In Congress, the White House wants the money approved quickly; Democrats want hearings first.
