MIDLAND, Mich. -

U.S. Rep. Dave Camp says he's considering whether to run for the Senate seat opening up with the retirement of Michigan Sen. Carl Levin.

Camp's office confirmed Wednesday that the chairman of the powerful House Ways and Means Committee is weighing a bid in 2014. He had previously ruled out running.

The only declared Republican candidate is former Secretary of State Terri Lynn Land.

Camp, a 60-year-old from Midland, has more than $3 million in his campaign account and has served in the House since 1991. A spokeswoman says there's no timeline for Camp to make a decision.

The only declared Democratic candidate is U.S. Rep. Gary Peters of Bloomfield Township.

Camp's decision to consider running was first reported by Politico.
