Well, it certainly tracks that Rep. Katie Porter was a student of Senator Elizabeth Warren's at Harvard. The clear and incisive questioning of those who'd dismiss the importance of knowing the ins and outs of finance and how it impacts the average consumer shone through, as always, while Rep. Porter was on her game.

Rep. Porter was questioning the Director of the Consumer Finance Protection Bureau (CFPB,) Kathy Kraninger, when she asked the Director a simple question about how to calculate the amount of a loan payment or amount financed. Kraninger hemmed and hawed, and Porter whipped out her trusty "Teacher's Manual" to help her along with the simple math. The amount financed involves one simple subtraction problem, and the amount of the loan payment involves one simple division problem.

Apparently this added up to a LARGE problem for the GOP on the committee, who whined about Porter's "props," and it was especially a problem for Kraninger, who said she didn't have her staffers on hand to figure it all out. Porter responded,

LISTEN. You would THINK these people would know better by now not to come to a hearing with Rep. Katie Porter without having done their homework to the fullest, and having had their parents check it over TWICE for errors. Otherwise, you end up looking like this fool.
