Klobuchar's remarks came in response to a question about her attack on Buttigieg during last Thursday's debate.

The senator hit the South Bend, Ind. mayor for what she said was him mocking "100 years of experience on the stage."

Defending her remarks, Klobuchar on Sunday touted some of her opponents' achievements.

"I pointed out to him that experience does matter, that is how we got the Consumer Financial Protection Bureau because of Elizabeth's work," she said, referencing Sen.
