Lawmakers left Washington for a long weekend without resolving an impasse over much-criticized agency’s funding

The Department of Homeland Security has begun a partial shutdown, after funding for the much-criticized agency expired, with a range of services, including domestic flights and the US Coastguard, now vulnerable to disruption.

The shutdown was all but confirmed on Thursday, after the Senate failed to clear the 60-vote threshold needed to pass the DHS appropriations bill and lawmakers left Washington for a long weekend without resolving the impasse.
