On June 3, the day of the final primaries in South Dakota and Montana, Obama rolled out about sixty superdelegate endorsements. Those endorsements, together with the pledged delegates awarded in the final primaries, put him well over the "magic number" of 2,117 delegate votes necessary for a majority at the Democratic National Convention. By early in the evening, all major news organizations had announced that Obama had clinched the Democratic nomination, and Obama claimed the status of presumptive nominee in a speech in St. Paul, Minnesota. Clinton did not concede the nomination in her election night speech, saying that she would be "making no decisions tonight".[121] On the morning of June 5, Clinton posted on her website an open letter to her supporters, which she also sent by e-mail that day. It announced that on Saturday (June 7) Clinton would endorse Obama's candidacy. During a well received concession speech in Washington DC on Saturday June 7 Clinton endorsed Obama in the following terms: "The way to continue our fight now, to accomplish the goals for which we stand is to take our energy, our passion, our strength, and do all we can to help elect Barack Obama, the next president of the United States. Today, as I suspend my campaign, I congratulate him on the victory he has won and the extraordinary race he has run. I endorse him and throw my full support behind him."
