Retirements mount in Congress: Some are frustrated by "chaos," and others seek new careers — or rest

Congressman Earl Blumenauer, an Oregon Democrat, is one of nearly 40 lawmakers leaving Congress at the end of this term. 

"I deeply respect some of my colleagues on both sides of the aisle, but it's harder and harder to work with them," Blumenauer told CBS News. "The unending chaos in the House really takes up most of the oxygen."

"The dysfunction in the House is part of the reason why I've decided to leave," said GOP Rep. Ken Buck, of Colorado. "People are lying a lot. And when you call out the lies, you're the bad guy. I feel like I can do more outside of Congress than inside of Congress."
