PALM DESERT, Calif. (AP) — Michelle Obama and three former first ladies were among dignitaries heading to California to pay tribute to Betty Ford at a funeral focusing on her twin passions: politics and her world famous Betty Ford Center for substance abuse and alcohol treatment. Ford, who died at the age of 93 on Friday, had mapped out plans for Tuesday's ceremony including who would deliver her eulogies. She chose former first lady Rosalynn Carter and journalist Cokie Roberts as speakers along with a former director of the Betty Ford Center.
