WASHINGTON (AP) — Elizabeth Warren is pledging that if she’s elected president, her secretary of education “will be a former public school teacher who is committed to public education.”

Warren made the vow in an email to supporter on Monday ahead of remarks at a town hall with members of the American Federation of Teachers union. The Democratic presidential candidate and Massachusetts senator is a former special education teacher who often talks about her early hopes to work in education.

Warren’s promise to appoint a former teacher came as she jabbed President Donald Trump’s education secretary, Betsy DeVos, who has no teaching experience. DeVos has come under fire from Democrats for multiple decisions, including her move to ease regulations on for-profit colleges. But Warren noted that “this problem is bigger than Betsy DeVos.”
