John Schindler, the former National Security Agency analyst and an outspoken critic of Edward Snowden, resigned Monday from his position as a professor at the US Naval War College months after a picture of his alleged penis surfaced online. The professor of national security affairs announced via Twitter his resignation from the Rhode Island institution, effective August 29.

"Sorry to say I'm severing my affiliation with Naval War College. I had a great time there but it's time to move on. Thanks for your support," Schindler tweeted.

A former National Security Agency analyst who was part of a task force that believed Saddam Hussein maintained weapons of mass destruction, Schindler was employed by the college since 2005. He was put on leave in June as the college ordered an investigation to determine whether the picture of his genitalia was falsified.

In June, a text message conversation with "John Schindler" at the top circulated widely on Twitter. The picture was accompanied with the message: "Got this?" It has not been revealed of who posted the text message conversation.

A college spokeswoman, Cmdr. Kelly Brannon, refused to disclose the inquiry's findings. She told The Washington Times that Schindler was notified of the results in late July.

Schindler had often criticized Snowden, the NSA leaker, and journalist Glenn Greenwald. In December, Schindler said on MSNBC that "Passion is nice, passion is good. Joseph Stalin was passionate. Adolf Hitler was passionate. We just buried Nelson Mandela who showed us how to enact passion in the cause of justice. Is what Edward Snowden is doing about justice or about a personal agenda? I'd really like to know."

Schindler's e-mail bounced, and he could not be immediately located for comment.

UPDATE: Schindler says it was "nonsense" to say the task force claimed that Hussein had WMD, although he notes that they did believe as much.
