SIOUX FALLS, S.D. (AP) — Former U.S. Senator Larry Pressler is running again for the Senate as an independent.

The 71-year-old served three terms as a Republican from 1979 to 1997. He lost a 1996 re-election bid to Democrat Tim Johnson, who is not seeking re-election next year after also serving three terms.

Pressler announced his intention to run Thursday in Sioux Falls.

KDLT-TV reports he describes the current political system as poisoned. Pressler says the country's prolonged role in foreign wars and the NSA's overuse of power are some of his main reasons for running.

He also says that an independent, he would have more power in Washington and promises to serve only one six-year term if elected.

Four Republicans and one Democrat are also running for the Senate seat.
