Treasury Secretary Steven Mnuchin on Thursday declined to say whether the Trump administration would continue with a plan to depict Harriet Tubman on the $20 bill.

Asked during a CNBC television interview about removing President Andrew Jackson from the currency in place of Tubman, an abolitionist and former slave, Mnuchin said: “It’s not something that I’m focused on at the moment.”

The most important reason to make currency changes is to stop counterfeiting, he said.

“People have been on the bills for a long period of time,” he said. “This is something we’ll consider. Right now, we have a lot more important issues to focus on.”
