On Thursday, Rish announced he will seek to retain his Senate seat in the 2014 election.
"I will run for re-election in 2014," Risch said. "When I ran for this office just over four years ago, I said our country was facing many challenges. Those challenges not only remain, they have gotten worse."
Risch was an Ada County prosecuting attorney before being elected to the Idaho State Senate in 1975, serving through 1988. He returned to the state Senate in 1995 and in 2002 he was elected lieutenant governor. Risch was re-elected in 2006 after serving as Idaho's 31st governor.
He was elected to the United States Senate in 2008.
