# Trump authorises National Guard deployment to Chicago amid legal fight

US President Donald Trump authorised the deployment of 300 National Guard personnel to Chicago on the event date, saying the move was needed to address what he called out-of-control crime. The decision came hours after immigration officials said they had confronted protesters in the city during unrest linked to ramped-up enforcement.

The BBC says the administration’s plan immediately raised legal and constitutional questions. National Guard troops are usually deployed by state governors, and older federal laws place limits on how the military can be used domestically. Illinois Governor JB Pritzker said Trump was trying to manufacture a crisis, while Democrats have repeatedly called the troop plans an abuse of power.

Chicago is only the latest city drawn into the dispute. The report says the administration has also targeted Washington DC, Los Angeles, Memphis and Portland for similar deployments. A federal judge in Portland blocked a deployment there, saying Trump’s claims about conditions in the city were untethered to the facts and warning that using the military without state consent risked blurring the line between civil and military power. The Trump administration has filed a notice saying it will appeal.

The Chicago decision also comes after a violent episode at the weekend. The Department of Homeland Security said Border Patrol personnel shot an armed woman after a group rammed cars into law enforcement vehicles. DHS said the woman was armed and that agents fired defensive shots after being unable to move their vehicles. Her injuries were unclear, though the agency said she drove herself to a hospital. That incident has become part of the administration’s argument that the city is facing a serious security threat.

Trump has threatened for weeks to send troops to Chicago, citing crime and shootings. But the BBC report also notes that violent crime in the city has fallen significantly over the past two years, including a one-third drop in homicides in the first half of the year compared with the same period last year. That does not mean Chicago is free of violence. It does mean the White House is presenting a public-order rationale that is more contested than the headlines suggest.

The deployment fight is now about more than Chicago. Trump said he would consider invoking the Insurrection Act if courts blocked him from using troops in US cities. That law, dating to 1807, would give the president broad power to use military forces inside the country to suppress rebellion or enforce the law. For opponents, the issue is whether the president is stretching those powers beyond their intended limits. For supporters, it is a test of whether federal authorities can respond to unrest when local leaders resist. The Chicago order has therefore become another flashpoint in a widening national dispute over the boundaries of domestic military power.
