A federal judge ordered the Trump administration Tuesday to immediately improve conditions at a New York City immigration holding facility, acting on complaints by jailed migrants that it is dirty, smelly and overcrowded.

A federal judge said he would block the Trump administration from using a Manhattan federal building to hold immigrants facing deportation unless it improves conditions there.

Lawyers representing detainees put forth allegations of cramped and unsanitary conditions, such as open-air toilets and a lack of beds or mattresses.
