Stephen Miller, one of President Trump's top advisers, went further, calling Preddy a would-be assassin and a domestic terrorist.

Administration officials made similar claims, with no evidence, about Renee Good, who was killed in her car by an ICE agent in Minneapolis earlier this year.

Minnesota Governor Tim Walz said he had called the White House to demand that the state handle the investigation into Preddy's death, saying the federal government cannot be trusted.

Despite that, state authorities say they've been cut out again, like they were after Good's killing.

Over the weekend, they took the extraordinary measure of getting an emergency court order to bar federal officials from destroying any evidence.

Still, they say they haven't received basic facts from the government, like the identities of the agents who opened fire.

In Washington, meanwhile, the uproar over Preddy's killing could lead to a partial government shutdown at the end of the week.

The Senate was set to vote on legislation that funds a broad range of government programs.

But some key Democrats now say they're opposed to it, since it includes over $60 billion for DHS, including $10 billion specifically for ICE.

Senator Angus King, an independent from Maine, where federal agents have also launched a ramped-up immigration enforcement operation, said on CBS yesterday that he shared Democrats' concerns and that ICE funding should be voted on separately.

At least one Republican senator has also raised concerns about the shooting.

Bill Cassidy of Louisiana said it was incredibly disturbing and called for a joint federal-state investigation, saying, quote, the credibility of ICE and DHS are at stake.

The gigantic winter storm that crossed over much of the U.S.

this weekend brought record-breaking low temperatures, dumped more than a foot of snow in 17 states, and knocked out power for hundreds of thousands of people.

The National Weather Service said Bonita Lake, New Mexico, got the most snow of anywhere in the country, recording 31 inches.

The heavy snow, combined with ice in the south, caused chaos for travelers.

Yesterday, nearly 40 percent of all flights in the country were canceled.

The storm also turned deadly in some states.

At least 11 people from Texas to New York died amid the bitter cold.
