Senate leaders were scrambling on Friday to save a bipartisan spending deal and prevent a partial government shutdown this weekend as some Republicans pushed back on a rare deal between President Donald Trump and Democrats. Democrats who are demanding new restrictions on federal immigration raids across the country struck an agreement with Trump on Thursday to separate funding for the Department of Homeland Security from a broad government spending bill and give Congress two weeks to debate the issue. That agreement came after irate Democrats threatened to block the entire spending bill and trigger a shutdown in the wake of the deaths of two protesters at the hands of federal agents in Minneapolis.
