WASHINGTON (Reuters) - The U.S. Justice Department has canceled hundreds of ongoing grants that funded everything from services for mental health care for police officers to support programs for victims of crime and sexual assault, according to internal records and four people familiar with the matter.

Advocates warn the loss of federal funding will jeopardize programs that help crime survivors heal and prevent cycles of violence in California communities.

Some of the hundreds of grants were mysteriously reinstated, but it’s unclear how many or why they were cut in the first place.
