Mr. Trump also put a portrait of Jackson in the Oval Office.

The Obama administration initially announced that it wanted to put a woman on the $10 bill, but a public outcry against the replacement of Alexander Hamilton, the incumbent frontman, prompted a change in plans. In April 2016, then-Treasury Secretary Jacob J. Lew announced that Jackson would move to the back of the $20 bill. He also said that images of women would be added to the back of the $5 and $10 bills.

Mr. Lew said final designs would be unveiled in 2020, with production starting later in the decade. The government regularly redesigns paper currency to frustrate counterfeiters, but the people honored on the bills have remained the same for nearly a century. Other nations, notably Britain, regularly rotate honorees, though Queen Elizabeth II remains on all the bills.

Mr. Lew was aware when he made the decision to redesign the currency that its fate would rest with Mr. Obama’s successor. But he said then that he doubted it would be reversed.

“I don’t think somebody’s going to probably want to do that — to take the image of Harriet Tubman off of our money? To take the image of the suffragists off?” he said.

Treasury had earlier removed its “Modern Money” website that the Obama administration created to highlight its plans for the redesigned bills.

Harriet Tubman was born enslaved, escaped to freedom and then returned repeatedly to the part of Maryland where she grew up to lead other slaves to freedom. She served as a Union scout during the Civil War and later become a prominent advocate for giving women the right to vote.
