Sen. Joe Manchin said Wednesday he will vote “no” on President Trump’s pick to head the Department of Education, who he said lacks experience in public education.

Manchin, D-W.Va., is the latest Democrat to object to Betsy DeVos, a school-choice advocate and Republican fundraiser. Democrats have railed against DeVos as unqualified, while the GOP has countered that their opposition is being pushed by the teachers unions who don’t like her record of backing school vouchers and charter schools.
