At least one person was arrested after some protesters scuffled with police outside the DC public school where Betsy DeVos paid her first visit as education secretary Friday.

In a bid to mend fences with educators after a bruising confirmation battle, DeVos visited Jefferson Middle School in southwest DC. About 50 protesters gathered outside the school, holding signs and shouting "We fight back!"

At one point DeVos was blocked from entering the building.

DeVos has previously worked to promote charter schools and school voucher programs, which her critics say would hurt public schools. She was confirmed for the job by the Senate on Tuesday by the narrowest possible margins, after two Republicans opposed her.

Journalists were prevented from entering the school to cover the event.
