More than 200 women who work on national security for the U.S. signed an open letter saying that they have survived sexual harassment and assault or know someone who has experienced it. Signed by current and former diplomats, civil servants, servicemembers and development workers, the letter calls for stronger sexual harassment reporting, mandatory training and outside data collection on how often it occurs. “This is not just a problem in Hollywood, Silicon Valley, newsrooms or Congress,” reads the letter, which was shared with TIME.
