The partial US government shutdown has become the longest in American history, as lawmakers in Washington continue to fight over funding for the Department of Homeland Security (DHS).

On Sunday, the shutdown reached 44 days, surpassing the previous longest funding lapse, which ended in November 2025.

The current impasse has led to chaos at airports, due to a shortage of Transportation Security Administration (TSA) officers at security checkpoints as employees go without pay cheques.

Congress is now on a two-week break so a deal to fund the DHS - which covers TSA agents, as well as immigration agencies - appears unlikely to pass any time soon.

On Friday, lawmakers failed to agree a deal to re-open the DHS, which has been shut since 14 February.
