Middletown South High School history teacher Joe Ventre showed his class a satirical video from the HBO show "Last Week Tonight" starring John Oliver.
The video already has over 24 million views on YouTube.
It bashes and lampoons the front-running presidential candidate regarding his family history, business dealings and politics.
School administrators, after hearing a complaint, asked Ventre to resign after the school year for bringing his personal political views to class. He resigned immediately, but rescinded his resignation just days later.
