A U.S. Coast Guard Academy official resigned ahead of a congressional hearing for Coast Guard leaders this week, alleging that she was instructed to lie to past victims of sexual assault at the academy to prevent Congress from learning about their experiences.

The Coast Guard deceived me into violating a basic principle of my profession, which is to never lie to victims, Shannon Norenberg, who served as the sexual assault response coordinator at the Coast Guard Academy since 2013, wrote in a blog post announcing her resignation Sunday.

Norenberg said she hoped to right a wrong and publicly apologize to the victims she says she misled after she was called in 2018 to assist the Coast Guards Operation Fouled Anchor investigation, which secretly examined and documented years of harassment and assault allegations within the military branch.
