Sen. Elizabeth Warren (D-Mass.) says the middle class is “not a numbers issue” and “doesn’t need a dollar figure” to define it.

A Boston television reporter covering Warren’s swearing-in on Thursday, Jan. 3, asked her: “When you mention middle class, what numbers are we talking in terms of income level?”

“It’s not a numbers issue, Warren responded. “I know you would expect a very wonky answer from me about the percentiles, but it’s not.”

Warren campaigned for the U.S. Senate as a champion of the middle class and says she comes from a “hard-working middle-class family.”
