Donald Trump's border czar is blaming news leaks for hindering a large-scale immigration operation in Colorado.

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.

The largest U.S. government worker union and an association of foreign service workers sued the Trump administration on Thursday in an effort to reverse its aggressive dismantling of the U.S. Agency for International Development.

Hundreds of supporters and workers for the US Agency of International Development rallied outside the Capitol Wednesday afternoon, demanding the agency be left alone.
