Florida Atlantic University has taken steps to fire a professor who claimed the massacre of children in Newtown was staged.

The school said in a release on its website that School of Communication and Multimedia Studies professor James Tracy was served a notice of termination Wednesday. The university said Tracy has 10 days to respond.

Although the school gave no reason for the action, the parents of one student killed at Sandy Hook recently claimed in a Florida newspaper opinion piece that Tracy was taunting them.

Tracy was reprimanded in 2013 for writing in his blog that the Sandy Hook killing was staged, and he has questioned accounts of other mass slayings.

Tracy declined comment in an email Thursday.
