The US House of Representatives is poised to end a partial government shutdown after President Donald Trump urged Republicans to press ahead with a vote despite concerns with the new spending plan.

Democrats and Republicans disagree over funding for the Department of Homeland Security (DHS), which is under intense scrutiny after federal immigration agents shot and killed two US citizens in Minneapolis last month.

The proposed deal, brokered in the US Senate at Trump's urging and now before the House, would fund the government and buy lawmakers more time to haggle over the future of DHS.

The deal keeps DHS running for two weeks while lawmakers consider future funding and reforms to the agency.

The DHS encompasses multiple subsidiary agencies, including Immigration and Customs Enforcement (ICE), Customs and Border Protection (CBP), the Coast Guard and Secret Service.
