The Trump administration has branded Chicago a "war zone" to justify deploying National Guard soldiers despite opposition from local Democratic officials, intensifying a political crisis over an anti-crime and migration crackdown.

• President Donald Trump authorized the deployment of 300 National Guard soldiers to Chicago.
• The White House's attempt to deploy troops in Portland, Oregon, was blocked by US District Judge Karin Immergut, who ruled the deployment unlawful.
• A CBS poll found that 42 percent of Americans favor deploying the National Guard to cities, while 58 percent oppose it.
