Second Lady Karen Pence and U.S. Surgeon General Jerome Adams returned to Indiana Tuesday to highlight a new workplace drug rehabilitation program that is said to be the first of its kind.

Pence worked as an art teacher, and as Indiana's first lady she advocated for art therapy to help children being treated in hospitals.

Gov. Mike Pence and his wife Karen participated in the fair’s opening ceremony and the unveiling of the Bicentennial exhibit.
