What to know about National Guard deployments in Memphis and other cities

Judges have stalled President Donald Trump’s plans to deploy the National Guard in Chicago and in Portland, Oregon, but troops are now patrolling in Memphis, Tennessee, with the blessing of the state's governor. It was unclear how many troops have been deployed to Memphis. Trump has sent or discussed sending troops to other cities as well, including Baltimore; the District of Columbia; New Orleans; and the California cities of Oakland, San Francisco and Los Angeles.
