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.

Grantees have 30 days to appeal, and a small number of grants already have been restored, according to the department.

The Justice Department terminated hundreds of grants this week, effectively slashing the budgets for organizations across the country that assist crime victims and fight both gun violence and opioid abuse.
