Six mayors in the United States turned to Congress on Monday for help blocking the federal security forces President Donald Trump wants to send to the cities. According to the mayors, the presence of the security forces leads to increasing tensions in anti-racism demonstrations.

The deployment of the federal security forces is also illegal and without the permission of the local authorities, according to the mayors.

“We enlist the help of Congress to make clear that these actions are illegal and revolting,” the mayors of Portland, Chicago, Seattle, Albuquerque, Kansas and Washington said in a joint letter to the Senate and the House of Representatives.

Trump’s federal security forces have been in Portland for a long time, where demonstrators have been taking to the streets every day since the death of George Floyd in Minneapolis in late May to demonstrate against racism and police brutality. Portland security forces are being deployed to protect government property from “violent anarchists,” according to the United States Department of Homeland Security.

Trump wants to curb violence in large cities with federal troops

As part of Operation Legend, which Trump plans to use to reduce violence in the cities, the president announced last week that he would also send troops to Chicago, Albuquerque and Kansas City, among others.

This led to dissatisfaction among local administrators, who express concerns about, among other things, the cooperation between the federal security forces and the local police.

According to Oregon Governor Kate Brown, the actions of federal order troops in the state last week led to disproportionate violence. Subsequently, the United States Department of Justice announced that it was investigating the actions of federal troops in the area.
