Bernie Sanders endorsed Hillary Clinton at a campaign event Tuesday morning. The two appeared together at a campaign rally in Portsmouth, New Hampshire.

Bernie Sanders on Tuesday finally offered his long-awaited endorsement to presumptive Democratic presidential candidate Hillary Clinton, saying he would work hard to help her win the White House in November.

“Secretary Clinton has won the Democratic nominating process, and I congratulate her for that,” Sanders told a cheering crowd at a rally in New Hampshire, with Clinton at his side.

“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.”

Now, Sanders didn’t announce that he’s suspending or ending his campaign. Regardless, though, this event effectively brings a long and often contentious Democratic primary to a close and unifies the party around the shared goal of defeating the Republicans and their presumptive nominee Donald Trump.

Sanders has long made it clear that he has no interest in helping a Republican president, especially Donald Trump get elected. He may not agree with Clinton on everything, but he’s a whole lot closer to her than Donald Trump.
