Report: Women sexually abused at two thirds of U.S. federal prisons

The findings were just released by a U.S. Senate committee. 

It found cases of abuse in two thirds of U.S. federal prisons. 

Investigators looked closely at two facilities in New York City -- MCC in Lower Manhattan and MDC in Brooklyn. 

The report found that in both facilities, multiple employees abused women. In many cases, the women were abused multiple times over a period of months or years. 

The committee also found the Bureau of Prisons has failed to implement a law meant to prevent prison sexual abuse.
