With a partial government shutdown looming, Senate Democrats laid out a list of demands Wednesday for the Department of Homeland Security, including an enforceable code of conduct for federal agents conducting immigration arrests and a requirement that officers show identification as the country reels from the deaths of two protesters at the hands of federal agents in Minneapolis.

It remained unclear if President Donald Trump and Republicans would be willing to meet those demands, even as funding for DHS and a swath of other government agencies was at risk of expiring Saturday. Irate Democrats have pledged to block a spending bill unless their demands for reforms are met.

Senate Democratic leader Chuck Schumer said Wednesday that the legislation won't pass until U.S. Immigration and Customs Enforcement is “reined in and overhauled."

“The American people support law enforcement, they support border security, they do not support ICE terrorizing our streets and killing American citizens,” Schumer said.

With an uncertain path ahead, the standoff threatened to plunge the country into another shutdown just two months after Democrats blocked a spending bill over expiring federal health care subsidies, a dispute that closed the government for 43 days as Republicans refused to negotiate. That shutdown ended when a small group of moderate Democrats broke away to strike a deal with Republicans, but Democrats are more united this time after the fatal shootings of Alex Pretti and Renee Good by federal agents.

There’s a lot of “unanimity and shared purpose” within the Democratic caucus, Minnesota Sen. Tina Smith said after a lunch meeting Wednesday.

“Boil it all down, what we are talking about is that these lawless ICE agents should be following the same rules that your local police department does," Smith said. "There has to be accountability.”
