Education Secretary Betsy DeVos marked Teacher Appreciation Week with a social media video thanking educators -- who then demanded her resignation in tweet after tweet.

The education secretary urged Americans to show their appreciation by thanking a teacher, but her efforts backfired.

DeVos was met with furious anger by teachers and their supporters who believe she's undermining public education with her policies.
