Democrats have refused to relent on their demands for funding the Department of Homeland Security (DHS), despite attempts by Republicans to use the Trump administration's attack on Iran to pressure Democrats to compromise on funding the department. Democrats are insisting on changes to control Immigration and Customs Enforcement (ICE) and Customs and Border Protection after federal agents killed two Americans in Minneapolis. The DHS funding expired on Feb. 13, leading to a partial shutdown of the department that affects TSA, FEMA, the Coast Guard and cybersecurity. Democrats have been negotiating with the White House over changes to immigration enforcement to secure their votes to reopen the agency in full. However, Republicans have shown no interest in reopening DHS on a partial basis.
