In a speech of striking stubbornness, he ignored the history-making achievement of his Democratic rival, Hillary Clinton, who became the first woman in American history to clinch the nomination of major political party.

Mr. Sanders waited until 15 minutes into his speech to utter Mrs. Clinton’s name. He referred, almost in passing, to a telephone conversation in which he had congratulated her on her victories. At that, the crowd of more than 3,000 inside an aging airport hanger booed loudly. Mr. Sanders did little to discourage them.
