Following his son’s arrest yesterday amid Antifa assaults on Trump supporters, John Sheerin took to Facebook to voice his disdain for them, and support for Antifa. The NJ Department of Homeland Security recently designated Antifa a Domestic Terrorist organization.
John Sheerin identifies himself in the posts as a Principal with the Philadelphia School District. His Facebook identifies him as Teacher, School District of Philadelphia.
According to his Facebook page, Principal Sheerin has attended many Antifa events in Philadelphia in the past and may be a very active member of the group.
