The White House and House Speaker John Boehner sparred over immigration reform Tuesday, after the GOP leader declared that no one has worked harder than he has to fix the nation's border control system.

Boehner's remarks, at a news conference, drew a stinging rebuke from White House press secretary Jay Carney at his daily briefing.

"The idea that you can, oh, I don't know, declare yourself to have been more committed than anyone to improve our immigration system and then have nothing to show for it is a little laughable," Carney said.
