A professor alleged to be promoting conspiracy theories and denying the Holocaust has been suspended without pay by the University of Lethbridge.

Anthony Hall is suspended pending the outcome of an internal investigation into possible violations of the Human Rights Act, university officials said in a statement.

B'nai Brith Canada called for Hall's termination after questions about an anti-Semitic Facebook post made on his page by a third party. The group also alleges the professor uses his academic credentials to deny the Holocaust and promote various conspiracy theories.

The university has "reassigned" his classes, according to the statement released Thursday.

"As well, any graduate students supervised by Dr. Hall have been assigned a new faculty supervisor to ensure there is no disruption to the academic program of students. Students affected by this decision have been notified of this change already."

Earlier this week, Hall said there is a smear campaign against him.

"I'm being slandered, the University of Lethbridge is being slandered," Hall told CBC Radio's Calgary Eyeopener.

"Right now, it's on my shoulders to defend the University of Lethbridge and to defend for all the faculty in Canada, the principle of academic freedom, because that responsibility has been abandoned by the administration at my university and it's been left for me and it's appropriate that I do so."

Hall co-hosts a YouTube show called "False Flag Weekly News," which allegedly promotes the notion of a Zionist conspiracy to foster hatred of Muslims through "false flag" terror events, beginning with the Sept. 11 attacks. He also runs his own news website.
