The VP asked me very inappropriate questions during office hours while no one was around and I said 'no' multiple times. Did more investigation on my own to see if anyone else was effected by him and uncovered a lot. Made a report to HR and the VP was suspended during the investigation. The VP resigned the next day, but official email was sent out yet. I discovered he might be a pathological liar. What can I do from here so this won't happen again at other companies they might end up at???
