Officers from several U.S. federal agencies searched for illegal immigrants on Wednesday in Aurora, the Colorado city with a large migrant population where President Donald Trump laid out his immigration policies during his campaign.

Also Tuesday, Colorado Public Radio and CBS4 were among outlets that reported the U.S. military was preparing space at Buckley Space Force Base in Aurora for staging, processing and temporary holding of “criminal aliens” detained in ICE operations, according to a U.S. Northern Command statement.
