U.S. Education Secretary Betsy DeVos submitted her resignation to President Donald Trump on Thursday night over a mob attack on the U.S. Capitol, according to U.S. media report, making her the second major official to step down following Transportation Secretary Elaine Chao.

"That behavior was unconscionable for our country. There is no mistaking the impact your rhetoric had on the situation, and it is the inflection point for me." DeVos said in a letter to Trump published by several U.S. media outlets. "Impressionable children are watching all this, and they are learning from us."
