Speaker John Boehner (R-Ohio) on Wednesday accused President Obama of “shrinking from his responsibility to lead” and going “AWOL,” placing full blame for Washington’s dysfunction at the doorstep of the White House.

The Speaker opened his weekly press briefing with a withering assessment of Obama’s job performance, leaving no doubt that the 2012 campaign has now overtaken the legislative session in Congress.

“The president checked out last Labor Day,” Boehner said as he sharpened a critique he has made for weeks. “He’s spent the last six months campaigning from one end of the country to the other instead of working with members of both political parties here in Washington to address the serious challenges that our country faces. He is shrinking from his responsibility to lead.”
