It could have been a teacher just going off topic without the knowledge of the Superintendent. For those of us raised in public/government school there are teachers who teach with a political bias. (I condemn this though whether it be left leaning bias or right leaning political bias as I feel students time is better spent actually learning real skill.) Look at the bright side though the student definitely was given a heads up by someone cause they filmed the propaganda, and it got reported! I count it as a win. Still I encourage the parents to follow up with this definitely.
