UPDATE 2:30 a.m. EDT: Democratic presidential candidate Bernie Sanders vowed to stay in the race for the nomination till the party’s convention in Philadelphia later next month. Speaking in front of a roaring crowd in California, Sanders thanked supporters for “being a part of the revolution.”

We are in this TOGETHER. Thank you New Mexico, California, South Dakota, North Dakota, New Jersey and Montana! #NotMeUs — Bernie Sanders (@BernieSanders) June 8, 2016

“Next Tuesday we continue the fight in the last primary in Washington D.C.,” the Vermont senator said, despite erstwhile Secretary of State Hillary Clinton proclaiming her victory Tuesday.

“I want to congratulate Senator Sanders for the extraordinary campaign,” Clinton said in her victory speech. Sanders also said that he received a very “gracious call from Secretary Clinton” and congratulated her on Tuesday night’s victories.

Original story:

Bernie Sanders’ revolution is now effectively over. Although the Associated Press and other news outlets declared Hillary Clinton the presumptive Democratic presidential nominee on Monday night, Clinton waited until Tuesday to claim victory for herself.

Now, with votes still coming in from California and five other states Tuesday night, Clinton is sure to get not only enough superdelegates, but also enough pledged delegates to clinch the party's nomination. She gave a victory speech Tuesday during which she celebrated her historic win as the first woman to secure a major party’s presidential nomination in American history.

It is mathematically impossible for Sanders to overtake Clinton’s lead and win the nomination with pledged delegates at this point, but the Vermont senator has said he still hopes to convince superdelegates — party officials who can support whichever candidate they choose — to switch their allegiance to him before the Democratic National Convention next month.

Sanders was expected to speak in Santa Monica, California, at 10 p.m. local time (1 a.m. EDT). When he speaks, you will be able to watch his speech here or by watching the live stream below.

The Vermont senator had been hoping to finish the race with a strong night in California. He spent a significant amount of time and money campaigning there over the past few weeks, but as results came in Tuesday night, it looked like Clinton would win the state.

Before Sanders’ speech, the White House released a statement saying that President Barack Obama spoke to both Clinton and Sanders Tuesday evening, congratulating both candidates “for running inspiring campaigns that have energized Democrats, brought a new generation of Americans into the political process, and shined a spotlight on important policy ideas.”

The White House also said that, at Sanders’ request, Obama will meet with the Vermont senator on Thursday “to continue their conversation” about the issues relevant to working families.

“The president looks forward to continuing the conversation with Senator Sanders about how to build on the extraordinary work he has done to engage millions of Democratic voters, and to build on that enthusiasm in the weeks and months ahead,” the White House statement said.
