Sen. Elizabeth Warren (D-Mass.) has apologized to the Cherokee Nation after she released a DNA test last October in an attempt to prove she had Native ancestry.

Warren was previously quiet on the controversy that surrounded the release of the test, which upset tribal leaders ― though not all ― and made her the punchline of Republicans and President Donald Trump himself, who has repeatedly referred to her as “Pocahontas.” Tribal officials confirmed to Tulsa World that Warren had “reached out” in recent days, just as she is expected to make an announcement this month on her run for president.
