In June, after the last of the primaries had taken place, Obama secured the Democratic nomination for president, with the help of multiple super delegate endorsements (most of the super delegates had refused to declare their support for either candidate until the primaries were completed). He was the first African American to win the nomination of a major political party in the United States. For several days, Clinton refused to concede the race, although she signaled her presidential campaign was ending in a post-primary speech on June 3 in her home state of New York. She finally conceded the nomination to Obama on June 7. She pledged her full support to the presumptive nominee and vowed to do everything she could to help him get elected.
