(Roll Call) The chairman of the Armed Services Committee, first elected in 1978, is the longest-serving senator in Michigan history and will turn 80 before Election Day next year.
In a statement, Levin said the decision not to seek another term was "extremely difficult."
"I love representing the people of Michigan in the U.S. Senate and fighting for the things that I believe are important to them," he said. "As Barbara and I struggled with the question of whether I should run again, we focused on our belief that our country is at a crossroads that will determine our economic health and security for decades to come. We decided that I can best serve my state and nation by concentrating in the next two years on the challenging issues before us that I am in a position to help address; in other words, by doing my job without the distraction of campaigning for re-election."
