U.S. Sen. Mike Johanns, R-Neb., has said that he will not seek re-election in 2014. 

The Senate Agriculture Committee member said he wants a "quieter time" to focus on his family following a busy political career. Prior to joining the U.S. Senate, he served as his state’s governor and as President George W. Bush's agriculture secretary.

Johanns, 62, announced that he was retiring from the Senate after one term. He said he and his wife, Stephanie, had decided that the time had come to end a public career that has spanned more than half of his life. Stephanie Johanns is a former state legislator. Between the two of them, they held eight different offices over the course of 32 years.

Johanns is the second Senate Agriculture Committee member opting not to seek re-election. Sen. Tom Harkin, D-Iowa, made a similar announcement in January.
