WASHINGTON – Treasury Secretary Jacob Lew said Tuesday that the reaction to his plan to put Harriet Tubman on the $20 bill and add civil rights and suffragette leaders to U.S. currency has been “overwhelmingly positive.” “I have not been in a store or on the street since we have made the announcement when somebody hasn’t come up to me and thanked me and told me how important it is and what it means to them,” Lew said.
