A Republican congressman is trying to block the Treasury from redesigning U.S. currency, a move that could prevent the government from replacing Andrew Jackson on the front of the $20 bill with abolitionist Harriet Tubman.
Rep. Steve King of Iowa has offered an amendment to a spending bill barring the use of funds to redesign any Federal Reserve note or coin.
Treasury Secretary Jacob Lew announced the changes in April. Tubman would become the first African-American on U.S. paper currency and the first woman on paper currency in a century.
Alexander Hamilton's portrait will remain on the front of the $10 bill. The back is to be redesigned to feature Susan B. Anthony.
It wasn't immediately clear why King opposed the redesign. His office did not immediately respond to messages.
