Minnesota officials say the FBI has blocked their access to an investigation into the fatal shooting of a woman by a US Immigration and Customs Enforcement (ICE) agent.
People have taken to the streets of Minneapolis to protest the killing of 37-year-old Renee Good, who died on Wednesday after being shot in her car.
Minnesota Governor Tim Walz has accused the Trump administration of blocking state officials from involvement in the case, but the US vice-president said the investigation is a federal issue.
Officials have offered differing accounts of the incident, with the Trump administration claiming the ICE agent was acting in self-defense, while local officials say the woman posed no danger.
Homeland Security Secretary Kristi Noem has claimed the ICE agent shot Good multiple times because she was trying to run over the officer in her car.
The US Federal Bureau of Investigation said it would investigate the incident.
Minnesota's Bureau of Criminal Apprehension (BCA) said the FBI had initially agreed to a joint investigation with state officials but then reversed course and denied the state access to materials and evidence.
Without the ability to access all the necessary case materials and evidence, the BCA has reluctantly withdrawn from the investigation, the BCA's superintendent Drew Evans said in a statement.
Speaking at a news conference on Thursday, Walz said he was worried the federal government would not be able to carry out an unbiased investigation.
It feels now that Minnesota has been taken out of the investigation, Walz said. It feels very, very difficult that we will get a fair outcome.
Vice President JD Vance told reporters on Thursday that the investigation into the shooting was a federal issue, arguing it would go against precedent for a local official to be involved in prosecuting the case.
Videos of the incident show ICE agents approaching a car in the middle of the street, instructing the woman behind the wheel to exit the SUV. As the vehicle attempts to drive off, one of the agents points their gun at the driver and gunfire ensues.
At the scene of the crash, blood from the shooting could still be seen in the snow, with a vigil set up to honor Good, complete with candles and flowers.
Hundreds of demonstrators expressed their anger over the killing, with some calling for accountability for the actions of the ICE agent.
Those who knew Good described her as a compassionate poet and musician, highlighting the loss felt by the community.
The exclusion of state authorities from the probe is likely to undermine public trust, experts warn, while it may still be possible for state charges to be filed against the federal officer involved in the shooting.
