Rachel Dolezal resigned from her job as leader of the NAACP chapter in Washington State Monday days after accusations that she has been pretending to be a black woman for years, when her parents says she is white.

In an open letter sent to the NAACP’s members and executive committee, the former president wrote, “It is with complete allegiance to the cause of racial and social justice and the NAACP that I step aside from the Presidency and pass the baton to my Vice President, Naima Quarles-Burnley.”

“The movement is larger than a moment in time or a single person’s story,” she wrote. “I can see that a separation of family and organizational outcomes is in the best interest of the NAACP.”

On Sunday, Dolezal canceled a scheduled Monday meeting with the organization where she was going to address the accusations that cast doubt on her racial background. Instead, she posted an unsigned message on the chapter’s Facebook stating that the meeting was postponed “due to the need to continue discussing with regional and national NAACP leaders.”

Over the weekend, some current and former NAACP leaders called for her resignation and scheduled a protest. One member started an online petition asking for her resignation. Over 600 people signed the petition.
