Um...the prez is wrong to use the term "Pocahontas" as an invective. Consider the following, from Wikipedia but which can also be found elsewhere:

Pocahontas and her husband, John Rolfe, had one child, Thomas Rolfe, who was born in January 1615. The following year, Thomas' parents travelled to London.

Pocahontas and her father, Chief Powhatan, have many notable descendants, including Edith Bolling Galt Wilson, Woodrow Wilson's wife; American Western actor Glenn Strange, Las Vegas entertainer Wayne Newton as well as members of the First Families of Virginia, including George Wythe Randolph, Admiral Richard E. Byrd, and Virginia Governor Harry F. Byrd.

In 1907, Pocahontas became the first Native American to be honored on a US stamp. She was a member of the inaugural class of Virginia Women in History in 2000.

In July 2015, the Pamunkey Indian Tribe, descendants of the Powhatan chiefdom, of which Pocahontas was a member, became the first federally recognized tribe in the state of Virginia.

I find it difficult for a man descended from a whoremonger of the Klondike Gold Rush to cast aspersions about someone else.
