HARWOOD: Senator Rubio, 30 seconds to you.
The Tax Foundation, which was alluded to earlier, scored your tax plan and concluded that you give nearly twice as much of a gain in after-tax income to the top 1 percent as to people in the middle of the income scale.
Since you're the champion of Americans living paycheck-to- paycheck, don't you have that backward?
RUBIO: No, that's -- you're wrong. In fact, the largest after- tax gains is for the people at the lower end of the tax spectrum under my plan. And there's a bunch of things my tax plan does to help them.

Harwood did have to correct an error in an earlier tweet, but he was factually correct in the debate. Maybe the Federalist isn't the best place to get your information...?
