All charges against four activists who protested outside a federal building during last year’s immigration crackdown in Chicago have been dropped in an unusual hearing where a top federal prosecutor appeared to acknowledge grand jury misconduct by his office.

The Supreme Court has refused to allow the Trump administration to deploy National Guard troops in the Chicago area to support its immigration crackdown.

National Guard troops sent to Illinois by President Donald Trump can stay in the state and under federal control, but can’t be deployed to protect federal property or go on patrol for now, an appeals court ruled Saturday.

National Guard troops are patrolling in Memphis for the first time, as part of President Donald Trump’s federal task force.

A judge has blocked the deployment of National Guard troops in the Chicago area for two weeks, finding no substantial evidence that a “danger of rebellion” is brewing in Illinois.
