Gadsden says she jokingly referred to looking for a discreet hit man in one post and removed another comment that said she didn't want to kill any students but "Friday was a different story."
Gadsden says officials referred to the shooting at the University of Alabama-Huntsville earlier this month during the meeting.
A university spokesman wouldn't comment on Gadsden's claims, calling it a personnel matter.
East Stroudsburg is a state university in the Pocono Mountains.
