The U.S. Department of Education's Office for Civil Rights is investigating an allegation of racism at a New Hampshire elementary school.

A white couple says their adopted black daughter was bullied for her race at two Hampton elementary schools, starting in 2016.

A spokesman for the federal department confirmed to New Hampshire Public Radio an allegation from John and Julie Cochrane about their daughter, Kora, is being investigated.

The Cochranes have accused administrators of discrimination in how they handle complaints.

Kora's since been transferred to a private school.

Hampton Schools investigated earlier this year and ruled Kora's experience didn't meet their official definition of bullying.

A message seeking comment was left with the district superintendent. The superintendent and school board chair previously denied the case was mishandled or that the school infringed on Kora's civil rights.
