The mayor of Portland in Oregon has renewed his call for federal troops to leave the US city, accusing them of abusive tactics against protesters.
"They are sharply escalating the situation," Mayor Ted Wheeler told CNN on Sunday.
There have been nightly protests against police brutality in the city since the killing of African American George Floyd in Minneapolis in May.
The federal government has said it is trying to restore order in Portland.
Speaking to CNN on Sunday, Mayor Wheeler said there were "dozens if not hundreds of federal troops" in the city, adding: "Their presence here is actually leading to more violence and more vandalism.
"They're not wanted here. We haven't asked them here. In fact, we want them to leave," he said.
His comments echoed those of Oregon Governor Kate Brown, who described the presence of federal troops in the city as "purely political theatre" from the Donald Trump administration.
Ms Brown told MSNBC that she had asked the federal government on Tuesday to remove the troops, saying: "You are escalating an already challenging situation."
Their comments came after Oregon's attorney general filed a lawsuit against the federal government, accusing it of unlawfully detaining protesters.
In the lawsuit, Ellen Rosenblum requested a restraining order to stop agents from the Department of Homeland Security, US Marshals Service, US Customs and Border Protection and the Federal Protection Service from making any more arrests in the city.
"These tactics must stop," Ms Rosenblum said in a statement.
The lawsuit said the actions of federal officers violated protesters' ability to exercise their constitutional First Amendment right to assembly and, by seizing and detaining people without a warrant, also breached the Fourth and Fifth Amendment right to due process.

The US Attorney's office in Oregon said on Twitter that the fence aimed to "de-escalate tensions" between protesters and law enforcement officials and asked people to leave it alone.
Officers declared a riot outside the Portland Police Association building. It was set on fire.
The last week has seen a violent escalation between protesters and federal agents, deployed two weeks ago by Mr Trump to quell civil unrest.
A report from Oregon Public Broadcasting (OPB) this week contained detailed accounts of witnesses who had seen federal law enforcement officers dressed in camouflage emerge from unmarked vehicles, grab protesters without explanation, and drive off.
Video checked by the broadcaster shows a protester, Mark Pettibone, describe how on 15 July he was "basically tossed" into a van containing people in body armour.
Mr Pettibone said he was taken to a holding cell in a federal courthouse, where he was read his arrest rights. After he declined to answer queRead More – Source
