By 1963, she had become SNCC's administrative secretary and a full-time member of the central office staff working as a day-by-day organizer, financial coordinator, and administrator. She was in charge of the summer voter registration project in Mississippi and was responsible for the Sojourner Truth motor fleet, which provided civil rights workers transportation. The following year, she argued that blacks must maintain the dominance of the SNCC after the organization had become dependent on whites for financial and political help. She suggested that they recruit southerners and set a limit on how many northerners they accepted since they sometimes caused tension within SNCC. One of her coworkers believed she "had been anti-white for years," although others dispute this since later on in her involvement in SNCC, one of her closest friends was white. She maintained much of the black nationalist agenda without being anti-white.
