As a display of party unity, Bernie Sanders endorsed Hillary Clinton for President.

"Secretary Clinton has won the Democratic nominating process, and I congratulate her for that," he told the Portsmouth, New Hampshire audience on Tuesday. "She will be the Democratic nominee for president and I intend to do everything I can to make certain she will be the next president of the United States."

A few weeks ago, Clinton secured enough delegates to become the Democratic Party’s presumptive nominee. Following that, it was unclear whether Sanders would choose to stand behind her for the Nov. 8 election.

Sanders hopes the voters will stand behind Clinton, despite the two candidates "disagree[ing] on a number of issues."

"Together, we have begun a political revolution to transform America and that revolution continues," Sanders continued in his speech, standing beside Clinton. "Together, we continue the fight to create a government which represents all of us, and not just the one percent – a government based on the principles of economic, social, racial and environmental justice."
