Oklahoma U.S. Senator James Lankford has introduced a resolution calling for the removal of Andrew Jackson from the $20 bill.

Jackson, according to the Oklahoma Historical Society, is thought to be the architect of the program to remove members of the Seminole, Creek, Chickasaw, Cherokee, and Choctaw tribes from their ancestral homes.

That policy resulted in the forced relocation of millions of American Indians, as well as the deaths of thousands.

A press release from Lankford reads, "The Administration has already announced they will place a woman on the $10 bill in 2020. I support recognition of a historic American woman on the $20 bill and the removal of Andrew Jackson, since he began the Indian removal policies that forced thousands of American Indians off their ancestral homelands.”

Last summer Treasury Secretary Jack Lew announced that a significant woman from U.S. history would be put on the $10 bill.
