But in the end Sanders, who went head-to-head with Clinton for the Democratic nomination, voiced his support for the woman who will be the first to run for president of the United States for a major party.
Sanders took the mic at the Democratic National Convention in Philadelphia Tuesday after all the votes had been cast and Clinton had officially earned the nomination. He made a speech, hoping to push for party unity, as the crowd chanted his name.
“I move that the convention suspend the procedural rules, I move that all votes, all votes cast by delegates be reflected in the official record,” Sanders said.
“And I move that Hillary Clinton be selected as the nominee for the Democratic Party for president of the United States.”

After Sanders spoke, some of his supporters in the crowd could be seen in tears. The “Bernie-or-bust” movement has emerged with many Sanders supporters refusing to support Clinton as the Democratic nominee.
After he spoke, Clinton tweeted a clip of Sanders’ speech with the caption, “Stronger together.”
