Four fair housing organizations sued the Department of Housing and Urban Development and the Department of Government Efficiency on Thursday, faced with the sudden rescission of approximately 30 million in critical grant dollars.

The organizations — in Massachusetts, Idaho, Texas and Ohio — were among 66 housing rights nonprofits across the country that received a letter in late February informing them that key funding used to help individuals fight eviction and seek redress for discrimination had been cut off. The lawsuit was brought on behalf of a proposed class of the groups.
