Thursday’s 45-55 test vote came as Democrats have threatened a partial government shutdown when money runs out on Friday. In the deal under discussion, Homeland Security would still be funded but for a short time to allow for negotiations on the Democrats’ demands. As the negotiations continued, it was unclear whether all Democrats would agree to a temporary extension of the funding. And across the Capitol, House Republicans have said they do not want any changes to the bill they passed last week. “The package will not come back through the House without funding for the Department of Homeland Security,” according to the letter.
