The Senate unanimously moved to fund most of the Department of Homeland Security, except for Immigration and Customs Enforcement and part of Customs and Border Protection, in a rare overnight session.

The agreement would fund other DHS components, such as the Transportation Security Administration and US Coast Guard, but the House will still need to act before funded agencies within the department can reopen.

The move is meant to alleviate long lines at airports, while lawmakers continue to debate possible reforms to immigration enforcement by DHS.
