President Obama. Greg Sargent (The Plum Line) reports:

In an interview to air on NBC later tonight, Obama concedes she may have misspoke but that her larger meaning was clear and uncontroversial.

According to the NBC press release, Obama says:

"I'm sure she would have restated it. But if you look in the entire sweep of the essay that she wrote, what's clear is that she was simply saying that her life experiences will give her information about the struggles and hardships that people are going through — that will make her a good judge."
