I got called out for sharing a story about a doctor Mark Trozzi who apparently decided to blow the whistle on the COVID hoax. I have done some digging on Dr. Trozzi and found this from 2010.
Though I cannot verify his ER credentials, this link says he is an emergency doctor.

The post is apparently over 11 years old, so if someone is impersonating Dr. Trozzi or has hijacked his profile it seems to go back some time.
