WASHINGTON (CNN) - Republican Rep. Greg Walden of Oregon, the top Republican on the House Energy and Commerce Committee, announced on Monday that he will not seek reelection.
In his statement, Walden expressed confidence, however, that Republicans can get back the House.
"But," the congressman added, "I also know that for me, the time has come to pursue new challenges and opportunities."
The Oregon Republican is a former chairman of the House Republican campaign arm, the National Republican Congressional Committee.
The current chair of the NRCC, Republican Rep. Tom Emmer of Minnesota, called Walden "a class act and political juggernaut who will be sorely missed in Washington" in a statement reacting to the news.
