House Speaker John Boehner couldn’t help but get teary-eyed during an interview with “60 Minutes” that aired Sunday.

In a segment marking the 150th anniversary of the Capitol Dome, Boehner welled up when asked if he ever takes the place he works for granted.

“Never. Listen, for a guy who grew up mopping floors at my dad's bar, it's a pretty humbling experience,” Boehner replied, getting emotional as he spoke.
