Cha-Change. A new series of $20 bills will feature abolitionist Harriet Tubman on one side and retain the image of former President Andrew Jackson on the other. Tubman will be the first African-American to ever appear on U.S. paper currency and the first woman to do so in over a century. However, disappointed citizens took to social media and criticized the decision to feature both figures on the bill simultaneously. Jackson is known for his racist legacy as president.
