Former South Dakota Governor and Congressman Bill Janklow has died of brain cancer.

The 72 year old Janklow left a lasting mark on South Dakota politics by serving four terms as governor.

He was elected to the U.S. House in 2002, but later resigned after causing a fatal traffic accident in 2003.

The combative Republican was credited with saving railroad service in the state, attracting credit card banks to South Dakota, and connecting classrooms to the Internet.

South Dakota Governor Dennis Daugaard is requesting that all flags in South Dakota fly at half-staff, effective immediately, until Janklow's interment, which is expected to be sometime next week.
