Advocates say families with children among those detained in LA, Phoenix, New York, Seattle, Chicago and Texas

Federal authorities have arrested people at US immigration courts from New York to Arizona to Washington state in what appears to be a coordinated operation, as the Trump administration ramps up the president’s mass deportation campaign.

On Tuesday, agents who identified themselves only as federal officers arrested multiple people at an immigration court in Phoenix, taking people into custody outside the facility, according to immigrant advocates.
