Trump authorises deployment of 300 National Guard troops to Chicago

Donald Trump has ordered the deployment of 300 National Guard members to Chicago, the latest in a string of cities where US troops have been sent.

White House spokeswoman Abigail Jackson confirmed the US president authorised the move, citing what she called "ongoing violent riots and lawlessness" that local leaders have not quelled. "President Trump will not turn a blind eye to the lawlessness plaguing American cities," Ms Jackson said.

Chicago is the latest city in the US where Mr Trump has authorised the deployment of US troops, as it follows similar orders for Los Angeles, Washington and Portland. Democratic governor JB Pritzker branded the move unnecessary and "a manufactured performance - not a serious effort to protect public safety".

The Illinois governor said in a statement: "This morning, the Trump administration's Department of War gave me an ultimatum: call up your troops, or we will. "It is absolutely outrageous and un-American to demand a governor send military troops within our own borders and against our will."

The plaintiffs said a deployment would violate the US constitution as well as a federal law that generally prohibits the military from being used to enforce domestic laws. Mr Trump ordered the deployment of troops to "war-ravaged Portland" last week, authorising the use of "full force" if needed.

The move came after a gunman opened fire on an Immigration and Customs Enforcement (ICE) field office in Dallas, wounding two detainees and killing another. Mr Trump sent the National Guard to Los Angeles over the summer and to Washington DC, as part of his law enforcement takeover there..
