Civil rights advocates, politicians and religious leaders are paying tribute to the widow of slain civil rights leader Martin Luther King Jr., Coretta Scott King, following her death early Tuesday.
Mrs. King's family said she died in her sleep at an alternative medicine clinic in Mexico. Doctors say the 78-year-old was battling ovarian cancer when she arrived in Mexico Thursday, and ultimately died of respiratory failure. Her body was returned to the United States earlier Tuesday.
A White House statement said the president and Mrs. Bush are deeply saddened by her death.
Secretary of State Condoleezza Rice called Mrs. King a champion of human rights, who gracefully balanced the demands of family with a career dedicated to non-violent social change.
The Reverend Jesse Jackson, who was with her husband when he was assassinated in 1968, called her a freedom fighter.
Mrs. King carried on her husband's work after his assassination, creating the Martin Luther King Jr. Center For Non-Violent Social Change in the southern city of Atlanta, Georgia.
