Ben Carson has a problem with abolitionist hero Harriet Tubman replacing President Andrew Jackson on the $20 bill. During a Fox Business Network interview Wednesday, the failed presidential candidate turned Trump surrogate lamented to Neil Cavuto that Jackson was "a tremendous president" and "in honor of that we kick him off the money." Asked whether he is, by extension, anti-Tubman, the retired neurosurgeon replied: "No. I love Harriet Tubman, I love what she did. We can find another way to honor her. Maybe a $2 bill?" The U.S. two-dollar bill is famously low in public circulation and seldom used.
