Shortly after orchestrating the longest federal government shutdown in U.S. history, congressional Democrats are once again threatening to hold the funding of the government hostage in a bid to cripple immigration enforcement efforts.

Following the death of 37-year-old Renee Good during an altercation with U.S. Immigration and Customs Enforcement (ICE) officers in Minneapolis last week, Democrats in both the House of Representatives and the Senate are suggesting potentially refusing to agree to pass a key funding package that includes funding for the Department of Homeland Security (DHS) unless their demands for increased oversight are met.

According to multiple reports, Democrats are weighing whether to allow another government shutdown to impose new regulations on ICE, with some senior party members instead suggesting other means of achieving their goals. Rep. Dan Goldman (D-N.Y.), for example, is eyeing the use of policy “riders” attached to legislation to prohibit federal funding from being used for certain activities, such as mass deportations. “There’s always the possibility of some degree of funding, but it’s also — you could put a rider in about restrictions or conditions … using funding to say that you can say no funding can be used for X, Y or Z,” Goldman said, according to The Hill. “We are going to continue to press, and I think there is a pathway to accountability through the appropriations process.”

Good was shot and killed by an ICE agent on January 7 while accelerating her SUV into the agent, after having obstructed ICE operations in Minneapolis and refusing to comply with law enforcement officers’ order to vacate the scene. A number of top Democrats have characterized the ICE agent’s actions as “murder,” while President Donald Trump and his administration have defended the use of force as an act of self-defense. Nonetheless, Democrats have seized on the headline-grabbing event to call for largely-unrestricted oversight over DHS and ICE, including banning ICE agents from wearing face masks and requiring agents to present warrants prior to making arrests.

“We should not be giving money for an increase in the ICE budget,” said Rep. Ro Khanna (D-Calif.), according to The Hill. “We should be fighting this,” he added. Senator Chris Murphy (D-Conn.) has led the charge against DHS funding, calling on his fellow Democrats to back legislation heavily restricting ICE agents’ actions and jeopardizing their safety, including by limiting their use of firearms. “It’s hard to imagine how Democrats are going to vote for a DHS bill that funds this level of illegality and violence without constraints,” Murphy told Axios, referring to the shooting in Minneapolis. “There’s gotta be some reasonable constraints.”

“Democrats cannot vote for a DHS budget that doesn’t restrain the growing lawlessness of this agency,” Murphy said later. Rep. Pramila Jayapal (D-Wash.) added, “We can’t just keep authorizing money for these illegal killers. That’s what they are, this rogue force.”

Other Democrats have gone as far as to call to impeach Homeland Security Secretary Kristi Noem. In a statement demanding Noem’s impeachment, Rep. Sean Casten (D-Ill.) alleged that Noem and DHS have “sanctioned the murder and baseless arrest of American citizens, endangered communities throughout Illinois and the United States, subjected human beings to shockingly inhumane conditions in the name of racism and xenophobia, and denied due process to citizens and non-citizens alike.” He continued, “The murder of Renee Good is a tragic episode in a story of harm and destruction orchestrated by Secretary Noem and ICE that must not be tolerated anywhere.” The congressman added, “I support immediate Congressional action up to and including impeachment proceedings, but that alone is insufficient. The entire chain of command who have enabled a culture of murder must face justice.”

However, Democratic leaders have been hesitant to endorse risking or triggering another shutdown so close on the heels of last year’s historically long shutdown, which lasted from October 1 until November 12. Senate Minority Leader Chuck Schumer (D-N.Y.) previously ruled out withholding DHS funding, while House Minority Leader Hakeem Jeffries (D-N.Y.) has similarly held off on supporting any proposals to fight Republicans over DHS funding.
