FLEMINGTON, N.J. – A New Jersey mother is demanding answers after a global studies teacher at Hunterdon Central Regional High School forbid students from using Fox News as a source in class.

The mother, who did not want to be identified, told LifeZette’s Flemington-based reporter Michele Blood that her son’s teacher only accepts CNN as a reliable news source.

“I’m livid,” the mother said. “I’m not allowing him to stay in this teacher’s classroom, to be subjected to this all year long.”

LifeZette is a news and commentary website founded by businessman Peter Anthony and Political commentator Laura Ingraham, a Fox News contributor, according to My Central Jersey.

The local mother took to Facebook to vent her frustrations about the situation, which she said was confirmed by other parents and students.

Students claim the teacher, who was not identified, told them Fox News reports are biased, and they should instead rely on the balanced coverage provided by CNN – the same news agency that was forced to issue a humiliating public apology when it falsely linked President Trump to a Russian bank this summer.

The president himself refers to CNN as “really fake news.”

Regardless, Flemington Borough Councilman Brian Swiggle told LifeZette the “disturbing injustice” is only the latest instance of liberal bias in local schools.

He said the incident illustrates of how students can become “brainwashed” by liberal activist educators, and encouraged parents to “push back hard.” Political bias in the classroom, Swiggle said, represents the “demise of our democracy.”

Superintendent Jeffrey Moore confirmed to NJ.com that the school is investigating the teacher’s comments, which occurred on the second day of school, September 7.

“We learned about a decision in a classroom to limit students to certain media sources in an assignment,” Moore wrote in a statement. “Without any delay, we partnered with parents to understand the needs of our students. We moved swiftly to address their concerns.”

“The Hunterdon Central Regional High School District is committed to affording students the freedom and respect they need to develop their own opinions,” he wrote. “In fact, we have policy that requires us to present all sides of any controversial issue.

“We recognize the potential for a teacher, as a trusted authority figure, to sway student opinion about such issues without even setting out to do so.”

It remains unclear what, if any, punishment the teacher may face.

Blood told New Jersey’s 101.5 FM that the concerned mother has yet to speak with the teacher about her bias, “but feels pleased with the responses so far from the superintendent, the principal and the 11th grade (vice principal).”
