Senate Democrats are threatening to withhold funding to the Department of Homeland Security in the wake of the latest civilian killing in Minneapolis. Federal immigration agents shot and killed Alex Pretti, a 37-year-old ICU nurse, on Saturday morning, the second time this month that federal agents have killed a civilian.On Capitol Hill, multiple Democratic senators warned that they would not approve a $1.2 trillion package to keep the federal government open if it includes appropriations for the DHS, according to NBC News. The bill was first approved in the House last week with the help of seven Democrats.“What’s happening in Minnesota is appalling—and unacceptable in any American city,” said Senate Minority Leader Chuck Schumer in a statement Saturday. “Democrats sought common sense reforms in the Department of Homeland Security spending bill, but because of Republicans’ refusal to stand up to President Trump, the DHS bill is woefully inadequate to rein in the abuses of ICE.”“Senate Democrats will not provide the votes to proceed to the appropriations bill if the DHS funding bill is included,” he added. The Democratic Party’s weakest links in the Senate have also voiced their refusal to support funding DHS. Nevada Senator Catherine Cortez Masto, who was one of eight Democrats to break with her party’s standoff over funding for the Affordable Care Act last year, said that other funding measures could pass, but not one for DHS.“The Trump Administration and Kristi Noem are putting undertrained, combative federal agents on the streets with no accountability. They are oppressing Americans and are at odds with local law enforcement,” Cortez Masto said. “This is clearly not about keeping Americans safe, it’s brutalizing U.S. citizens and law-abiding immigrants.”Senator Jacky Rosen, another Democrat from Nevada who broke with her party over the last shutdown, also said she opposed “any government funding package that contains the bill that funds this agency, until we have guardrails in place to curtail these abuses of power and ensure more accountability and transparency.”Senator Tim Kaine, a third former defector, came out against the bill even before Pretti’s killing. He argued that Congress shouldn’t validate a president who is “acting chaotically and unlawfully.”A few Republican senators have also criticized Pretti’s killing, calling for an independent investigation into the incident, but there has been no indication they intend to do anything to protect American citizens from ICE violence.
