Getting a fair outcome from an investigation into the shooting "feels very, very difficult," Minnesota Gov. Tim Walz lamented.

Within hours of an Immigration and Customs Enforcement agent fatally shooting 37-year-old mom Renee Nicole Good in Minneapolis, Homeland Security Secretary Kristi Noem told Americans she already had all the answers.

"It was an act of domestic terrorism," Noem announced during an unrelated press conference at the Texas border on Wednesday.

Good, who had not yet been identified, "attacked [ICE agents] and those surrounding them" and "attempted to run them over and ram them with her vehicle," Noem continued.

It was the first indication that President Donald Trump`s administration would be playing offense, not defense, over the shooting, by demonizing Good and pushing Minnesota authorities out of the FBI`s probe into the shooting.

As Noem spoke, footage of the incident was already circulating, and it didn`t back up her authoritative rhetoric about what unfolded. Multiple camera angles showed masked ICE agents approaching Good`s car as it partially blocked a road, grabbing at the door handle, reaching through the open window of her vehicle and then an officer (identified by The Star Tribune as Jonathan Ross) shooting her dead at close range as she tried to drive away from the agents, who, for the most part, lack legal authority to arrest U.S. citizens.

A witness to the incident told HuffPost Good was "obviously scared" and trying to get away from the agents. No video of the incident shows Good attempting to run over officers; it shows her turning her wheels away from them in the final moments of her life. It`s not clear if Good`s car made contact with the agent, who was seen in video footage walking away from the scene.

But even as additional footage of the incident emerged throughout the day, Noem ramped up her claims, baselessly suggesting Good was involved in a "coordinated" group that had been "trained and told how to use their vehicles to impede law enforcement operations."

Family told Minnesota Public Radio that Good was on her way home from dropping her 6-year-old son at school when she encountered the ICE agents. She was not an activist and was not known to be involved in protests, family said.

As the day wore on, more members of the Trump administration piled on the demonization of Good.

"[T]he woman driving the car was very disorderly, obstructing and resisting, who then violently, willfully, and viciously ran over the ICE Officer, who seems to have shot her in self defense," Trump claimed on Truth Social. It`s "hard to believe" the officer who killed Good is alive, he continued.

Trump didn`t back down when pressed by The New York Times, calling it a "vicious situation."

Vice President JD Vance slammed her as "a deranged leftist who tried to run him over" on social media. He doubled down during a Thursday press conference, claiming without any evidence: "That woman was part of a broader left-wing network to attack, to doxx, to assault and to make it impossible for our ICE officers to do their job."

In another social media post Thursday, he called reactions to her death "preposterous" and said Good`s death was her own fault.

Echoing Noem and Vance, White House press secretary Karoline Leavitt leaned into the conspiracy theory talk at the press conference with Vance, saying the shooting happened because of a "larger, sinister left-wing movement."

The rhetoric has outraged Democrats and surprised at least one Republican.

"I was surprised at the level of certainty in her comments ... most times you don`t draw definitive conclusions like she did in that press conference while the scene is still being processed," Sen. Tom Tillis (R-N.C.) said of Noem to HuffPost on Thursday.

Little Hope For Accountability

The Trump administration is denying state and local officials any access to the investigation into the shooting, offering little hope for a non-partisan probe into what happened.

"They don`t have any jurisdiction in this investigation," Noem said Thursday. She then railed against Minneapolis and Minnesota officials for not doing enough to assist ICE.

Her remarks came after Minnesota Bureau of Criminal Apprehension (BCA) Superintendent Drew Evans released a statement saying the U.S. attorney`s office has barred it from participating in the federal investigation.

"Without complete access to the evidence, witnesses and information collected, we cannot meet the investigative standards that Minnesota law and the public demands," Evans wrote. "As a result, the BCA has reluctantly withdrawn from the investigation."

It`s impossible for Minnesota to do its own investigation without the federal government`s cooperation, the state`s Department of Public Safety commissioner Bob Jacobson explained Thursday.

"They do have all the evidence in the original investigative notes and reports. We have none of that. They have shared none of that with us," he said. "We would welcome the opportunity to jump back in to ... find the answers that the public deserves. Without any of that information, without any of that assistance from the FBI or the federal government, we would be at a loss to be able to initiate and conduct a thorough investigation."

Noem said Thursday she`s already confident the investigation will clear the ICE agent of any wrongdoing.

"We have expected all the policies and procedures of review will be exactly that he acted appropriately to protect his life and the life of his colleagues," she said Thursday when asked to share more information about him.

Following Noem`s remarks, Minnesota Gov. Tim Walz (D) said getting a fair outcome from an investigation into the shooting "feels very, very difficult" now.

"I say that only because people in positions of power have already passed judgment, from the President to the Vice President to Kristi Noem, have stood and told you things that are verifiably false, verifiably inaccurate," a despondent Walz said at a press conference. "They have determined the character of a 37-year-old mom that they didn`t even know."
