Rep. Justin Amash (R-Mich.) will not run for the U.S. Senate next year, a spokesman confirmed Wednesday.
His decision likely paves the way for Terri Lynn Land, a former Michigan secretary of state, to run against challenge Rep. Gary Peters (D-Mich.), who plans to run to succeed retiring Sen. Carl Levin (D-Mich.).
Amash's decision also means that he will not join the growing number of younger, conservative tea party-backed senators elected in recent years who have spent most of this year attempting to slow or postpone bills under consideration.
This summer Amash led a bipartisan push in the House to defund part of the domestic spying program operated by the National Security Agency. The proposal was narrowly defeated, but attracted support from a mix of conservative and liberal lawmakers.
Amash, 33, has served in the House since 2011.
