Coast Guard Academy banned a retired captain from its grounds after CNN reported he sexted a student. Now more allegations are surfacing.

The US Coast Guard Academy on Friday announced it had banned a retired captain from its grounds following a CNN report this week that revealed the captain, who is now president of a small college, exchanged hundreds of sexually suggestive messages with a student more than a decade ago.

Coast Guard attorneys had recommended prosecuting Glenn Sulmasy, who previously served as a department chair at the academy, on charges of conduct unbecoming an officer and willful dereliction of duty in 2016, even though he had retired eight months earlier. Coast Guard leaders rejected that recommendation and Sulmasy went on to have a successful career in academia, first as a provost at Bryant University in Rhode Island, and more recently as president of Nichols College in Massachusetts.
