A federal judge expressed doubts toward those challenging the federal policy, a potentially favorable sign for President Trump as he seeks to clamp down on immigration.

A federal judge in Washington ruled against plaintiffs who challenged the Trump administration’s ability to transfer immigrants to the U.S. military base in Cuba, known as Guantánamo Bay.

Former immigration enforcement officials warned of the conditions, including the use of strip searches and shackles, approximately 290 migrants had been held in at the military base.
