The Trump administration on Wednesday rolled out a new plan that would allow the government to detain migrant families traveling with children indefinitely, effectively calling for an end to the federal government's agreement with a court more than 20 years ago that it wouldn't hold children for long periods of time because it's so detrimental to their health.

The Trump administration is moving forward with one of its most aggressive steps yet to restrict legal immigration, denying green cards to many migrants who use Medicaid, food stamps, housing vouchers or other forms of public assistance, officials said announced Monday.

A spokesman for U.S. Immigration and Customs Enforcement says nearly half of those arrested during the largest immigration raid in a decade in the United States have been released.

At least 40,000 migrants who have reached the U.S. border with Mexico are on waiting lists for an initial attempt to seek asylum or are waiting for a court hearing in the U.S. after being sent back.

The decision allows the Trump administration to implement for now its most ambitious effort yet to unilaterally overhaul the asylum system.
