On April 20, 2016 US Secretary of the Treasury Jack Lew penned an announcement on Medium:
[T]oday I am excited to announce that for the first time in more than a century, the front of our currency will feature the portrait of a woman — Harriet Tubman on the $20 note.
The Tubman change dominated headlines, but the Jackson-Tubman swap is a part of a larger, longer-term strategy:
We anticipate that final concept designs for the new $20, $10, and $5 notes will all be unveiled in 2020 in conjunction with the 100th anniversary of the 19th Amendment, which granted women the right to vote. [Emphasis added.]
