President Donald Trump has authorised the deployment of 300 National Guard troops to Chicago to address what he says is out-of-control crime.

The move came hours after immigration authorities faced off with protesters in the Democrat-run city, resulting in the shooting of an armed woman when she and others rammed their cars into law enforcement vehicles.

State and local leaders have criticized Trump's deployment plans as an abuse of power. Illinois Governor J.B. Pritzker accused Trump of trying to manufacture a crisis.

This announcement came as a federal judge in Portland blocked further troop deployment plans, claiming they violated constitutional principles and state sovereignty.

Chicago's protests have increased as demonstrators oppose immigration enforcement by U.S. Immigration and Customs Enforcement (ICE). The White House argues that the measure was necessary to address lawlessness in the city. Meanwhile, legal challenges regarding the deployment are anticipated.
