President Donald Trump signed legislation to fund the government again — putting an end to the longest government shutdown in U.S. history.

Trump signaled Monday the government would open soon, as consequences of a lapse in funding continued to snowball, including missed paychecks for federal workers and airline delays stemming from air traffic controller staffing shortages.

The bill keeps funding the government at the same levels during fiscal year 2025 through Jan. 30 to provide additional time to hash out a longer appropriations measure for fiscal year 2026.

The measure also funds the Supplemental Nutrition Assistance Program (SNAP) that more than 42 million Americans rely on through September. The program supports non- or low-income individuals or families to purchase groceries on a debit card.

Additionally, the measure reverses layoffs the Trump administration set into motion earlier in October and pays employees for their absence.

The reopening of the government comes after more than 40 days of a lapse in funding amid a stalemate between Senate Republicans and Democrats over a stopgap spending bill that would have funded the government through Nov. 21.

After a lapse in funding starting Oct. 1, the Senate passed legislation Monday night that would reopen the government by a 60–40 vote margin. A total of eight Democrats voted alongside their Republican counterparts for the measure. The House subsequently passed its version of the measure Wednesday.

The deal came as fallout from the shutdown came to a head, including travel disruptions at U.S. airports where air traffic controllers and Transportation Security Administration (TSA) officers were required to work and were gearing up to miss a second paycheck.

As a result, these staffers were calling in sick, or taking on second jobs, creating staffing shortages and flight delays.

The standoff between Republicans and Democrats originated over disagreements about various healthcare provisions to include in a potential funding measure. Trump and Republicans claimed Democrats wanted to provide illegal immigrants healthcare, and pointed to a provision that would repeal part of Trump’s tax and domestic policy bill known as the "big, beautiful bill" that reduced Medicaid eligibility for non-U.S. citizens.

Democrats pushed back on this characterization, and said they want to permanently extend certain Affordable Care Act subsidies that are set to expire at the end of 2025.

The stopgap spending bill that Trump signed does not extend these subsidies by the end of the year, but Senate Majority Leader John Thune, R-S.D., agreed to a vote in December on legislation that would continue these credits.

Even so, Speaker of the House Mike Johnson, R-La., has not agreed to get on board with that arrangement in the House.

The FBI was called Sunday after a loaded gun magazine was found on a Frontier Airlines plane at Hartsfield-Jackson International Airport in Atlanta.

Just after 4:30 p.m. Saturday, officers assigned to the airport responded to a call about a gun magazine found near Frontier Airlines Gate C-6 in Concourse C, according to a news release from the Atlanta Police Department (APD).

A passenger on the Airbus A320 aircraft discovered what appeared to be a loaded magazine containing ten hollow point rounds near seat 7A, according to the release.

Police said the magazine, marked with the initials "K H," was found during boarding for a turnaround return flight to Cincinnati.

Officers coordinated with TSA, DOA, Frontier Airlines, Homeland Security and Atlanta Police K-9 units, and the aircraft was deplaned, according to the release.

After a thorough search by officers, no additional items of concern were found.

TSA re-screened all passengers, and the flight departed safely just before 8 p.m., according to officials.

The FBI was notified of the matter, according to APD.

"No active threats were indicated at this time," the agency wrote in the release.

A Frontier Airlines spokesperson told affiliate FOX 5 Atlanta the ammunition belonged to a member of law enforcement who was on an earlier flight.

"Customers were asked to deplane while a security sweep of the aircraft was conducted, along with additional passenger screening prior to the flight’s departure," the airline told the outlet. "A subsequent investigation confirmed that the ammunition belonged to a law enforcement officer who was on an earlier flight on the same aircraft. The ammunition and magazine were taken into the custody of the Atlanta Police Department and the property owner was referred to Atlanta P.D. to retrieve his items."

However, an APD source told FOX 5 investigators have not confirmed who the magazine belonged to.

"I’ve heard of a lot of delays, canceled flights, but I’ve never heard of this before," passenger Terry Foster told the outlet. "This is brand new."

Another passenger, Janyia Davis, told FOX 5 she didn't feel anyone was in danger, but "something bad could still happen."

Frontier Airlines did not immediately respond to Fox News Digital's request for comment.
