Protests continued in Minneapolis and other US cities on Sunday over the fatal shooting by immigration agents of 37-year-old intensive care nurse Alex Pretti in Minneapolis on Saturday.
Minnesota Governor Tim Walz said America was at an inflection point and repeated calls for US President Donald Trump to remove federal immigration agents from the city.
The US president meanwhile called for the governor to turn over all Criminal Illegal Aliens incarcerated in state prisons for deportation.
Meanwhile Minneapolis Police Chief Brian O'Hara told the BBC that state officers were blocked from accessing the scene of the shooting by federal agents, despite securing a search warrant.
He added that all levels of law enforcement in Minnesota have been working with federal law enforcement for several years, and that the unfolding situation in Minnesota was hampering agencies' ability to continue such investigations.
US Border Patrol commander Greg Bovino on Saturday accused O'Hara and Frey of trying to derail federal law enforcement operations.
Trump signaled in an interview with the Wall Street Journal published on Sunday that he might be willing to eventually withdraw ICE agents from the Minneapolis area, but did not provide a time frame.
In the interview, the president added that his administration was reviewing everything about Pretti's death and said that it will come out with a determination.
Lawmakers continue to be divided over the shooting of Pretti, as well as his second Amendment right to bear arms.
US Homeland Security Secretary Kristi Noem said Pretti was shot because he was brandishing a gun. Local authorities say the gun was legally registered, he was not brandishing it, and he was shot after the gun was removed.
The Trump administration has described Pretti as a domestic terrorist.
Pretti's family issued a statement in response to the comment saying the sickening lies told about our son by the administration are reprehensible and disgusting.
The latest shooting follows weeks of tensions between the Minnesota authorities, federal agents and protesters who have taken to the streets to observe the agents during their anti-immigration raids. Earlier this month, an ICE agent shot dead Renee Good, a 37-year-old Minneapolis resident who was taking part in such an observation.
Trump's crackdown in Minneapolis was launched in December after some Somali immigrants were convicted in a massive fraud of state welfare programmes. The state is home to the largest community of Somali immigrants in the US.
