Gov. Bill Lee took the oath of office for a second term on Saturday, pledging to improve Tennessee’s transportation system, improve care for children in state custody, and improve protections for the environment.

Bright sunshine warmed the January morning as Lee, 63, was sworn in on War Memorial Plaza in Nashville. First Lady Maria Lee, who has been undergoing treatment for lymphoma for the last several months, stood by the governor’s side dressed in a powder blue coat and white fur hat. Tennessee Supreme Court Chief Justice Roger Page administered the oath.
