The unidentified teacher at Whitney High School in Rocklin, CA quickly came under fire after a parent shared a screenshot of the test question to social media.
"We all have different beliefs," Jessa Krissovich told Fox 40. "This is the United States and we all come from different backgrounds and everybody should be okay with who they are."
"These stories have gone in one ear and out the other. It sounded unbelievable."
On Saturday, Whitney High School principal Justin Cutts released a statement informing parents that the Whitney High School Administration Team and Rocklin Unified School District are "conducting a thorough investigation."
"While personnel matters will remain confidential, appropriate disciplinary steps will be taken," wrote Cutts, whose school is located roughly 25 miles northeast of Sacramento.
Another parent, who wanted to stay anonymous, told Fox 40 that one-sided political comments, mainly against the Republican Party, are common with this social science teacher.
"The question on the test is really blatant obviously and that's out there," the parent explained. "This has been the first time it has been looked at of him crossing the line."
Joel Alquicira, a former student of the teacher who administered the test, told KCRA: "I understand he's just trying to make a joke, but that kind of stuff shouldn't be on a test."
"He was always like a funny kind of teacher," continued Alquicira. "He would always make jokes."
The controversial test question comes as schools and parents across the nation proceed to debate students' curriculum, explicitly focusing on Critical Race Theory.
The Governor-Elect made the highly-debated curriculum a significant talking point of his campaign and credited his triumph to a "movement" of parents that started in Loudoun County.
"This campaign stopped being a campaign a while ago, and it became a movement," Youngkin told Tucker Carlson Wednesday morning in his first network interview since he was announced the winner, continuing that "education really did become a top issue in this election."
"Parents across Virginia started to recognize that they really did need to have an important, decisive role in their children's education," he went on. "And when they heard Terry McAuliffe say… he wants to put government between parents and their children, this ceased to be a campaign and it started to be a movement led by parents."
