Congress adjourned for the weekend Friday afternoon, guaranteeing the government shutdown will continue and become the longest in US history — as air traffic controllers sued the Trump administration over their frozen pay.

The shutdown will have dragged on for 24 days when lawmakers return to work Monday — smashing the 21 days set during the Clinton administration in 1995-96.

The news comes as the National Air Traffic Controllers Association hit the Trump administration with a lawsuit in DC federal court Friday, arguing the government has “unlawfully deprived” its members of their wages during the impasse — “devastating” their lives and putting passengers at risk.

The named plaintiffs in the suit include single mom Amanda Fuchs, who says that without her paycheck, she can’t afford needed physical therapy and her family won’t be able to attend her recently deceased grandmother’s funeral.

Fellow plaintiff Jonathan Barnett is a father of three young kids who says he can’t afford therapy for his 4-year-old son who has autism — and fears his family will be evicted if they’re late on paying rent.

The suit alleges the government is violating the Fair Labor Standards Act by failing to pay the workers at least minimum wage, as well as overtime, during the shutdown.

The House on Friday passed a Senate bill to ensure that all government workers will be paid retroactively once the shutdown ends, and the president is expected to sign the legislation.
