Kim Teehee was an intern combing through dusty archives when she first learned of a largely forgotten agreement between her Cherokee tribe and the federal government.
More than 25 years later, that document has placed Teehee at the center of a historic reckoning of the way Congress treats Native Americans, while raising questions about what representation in Washington really means.
It was a treaty, ratified by the Senate and signed by President Andrew Jackson in 1835, granting the Cherokee Nation a delegate to Congress.
