Bernie Sanders' campaign manager insists the U.S. senator is still an 'active candidate' for president, even though he's no longer pursuing superdelegate support - the only way he could win.

Thursday evening Sanders spoke to his supporters via livestream and did not drop out of the race while not explicitly saying he's still in.

Sanders danced around the issue, and an endorsement of Hillary Clinton, as he again pledged to fight for progressive values at the summer nominating convention.

Today on Morning Joe, Sanders campaign hand Jeff Weaver said, 'yes,' Sanders is still running for president, adding to the confusion.

'Yes, he is. Yes, he is. Yes, he is,' Weaver said, in response to a question about Sanders' status. 'He's an active candidate for president, yes,' Weaver said.

The last Democratic presidential primary was held on Tuesday, ending a months long process that saw Hillary Clinton win the popular vote. She also won a majority of pledged delegates.

She did not, however, win enough pledged delegates to become the Democratic nominee outright. For that, she'll need the backing of the party's superdelegates at the July convention.

Clinton has more than enough superdelegate support to become the party's nominee. With that in mind, President Barack Obama has already endorsed her.

Appearing on Bloomberg TV Thursday afternoon, before Sanders' address, Weaver disclosed that the campaign had stopped making calls to superdelegates and was no longer trying to lure them away from Clinton - but it was not until his interviewers badgered it out of him.

'There is a progressive agenda that he laid out. The country has a lot of needs. Those needs have not changed just because the voting has stopped. His life's work has been to advance those agenda items,' Weaver said the first time he was asked about the senator's status.

Income inequality, campaign finance reform, healthcare for all - 'those issues still exist,' Weaver said on Bloomberg's With All Due Respect.

He added, 'And the needs and the desires of the people who supported him, and the people who didn't who didn't support him, still exist, and he's gonna continue working on that though the convention.'

Weaver also went on about how the he expects a 'unified party' coming out of the Democratic National Convention and a discussion on site about 'substantive issues, some of which the candidates had sharp disagreements on in the course of the campaign.

Program host John Heilemann called him out for the 'vagueness' and asked directly if Sanders is still trying to win.

'Is he still campaigning to win the nomination or not?' Heilemann pressed. 'He still is a candidate for the Democratic nomination,' Weaver stated.

That would require the support of party officials with votes at the convention, however, and Weaver admitted, 'We are not currently lobbying superdelegates, we are not, no.'

'I don’t anticipate that will start anytime soon,' he said, begrudgingly, after he was further pressed to explain.

Sanders, during his much anticipated livestream address to his supporters Thursday night, did not not offer a concession to Clinton.

Instead he said he would start working to defeat Donald Trump soon in a new role that he didn't define.

'It is no secret that Secretary Clinton and I have strong disagreements on some very, very important issues,' Sanders told his tribe. 'It is also true that our views are quite close on others,' he said, playing both sides.

Sanders restated his goals and said he would take his 1,900 delegates to the convention in Philadelphia where the Democrats would pass 'the most progressive platform in its history and that Democrats actually fight for that agenda.'

'I also look forward to working with Secretary Clinton to transform the Democratic Party so that it becomes a party of working people and young people, and not just wealthy campaign contributors,' Sanders said.

'A party that has the courage to take on Wall Street, the pharmaceutical industry, the fossil fuel industry and the other powerful special interests that dominate our political and economic life,' he added.

On the other hand, he said, 'The major political task that we face in the next five months is to make certain that Donald Trump is defeated and defeated badly.'

'And I personally intend to begin my role in that process in a very short period of time,' he added, declining to say what that role is.

The speech capped off a strange set of 10 days in Democratic politics that began when the Associated Press and other networks declared on Monday, June 6, that Clinton had enough superdelegate support to win the nomination at the July convention.

The next day marked the last big primary election day, with only Washington, D.C. outstanding.

Clinton subsequently creamed Sanders in California, where he had staked his fortunes, though the race has tightened since then, as the remaining votes are being counted.

Either way, Clinton would still have earned a majority of pledged delegates and makes it to the magic number of 2,383 with her strong superdelegate support.

But Sanders refused concede after California, vowing to take the fight to D.C., even after President Obama named her the Democratic nominee.

He didn't concede when he arrived in Burlington, Vermont, last Wednesday, either.

Sometimes a trip home signals that a candidate is about to drop out - in Sanders' case, it turned out to be business as usual.

The next day he met with President Obama at the White House and delivered a statement in front of the building that suggested he would stay in through D.C. and then get out of Clinton's way.

Yet, he again declined to concede in Washington, D.C. after Clinton the contest on Tuesday, besting him in the capital city's by more than 50 points.

That night the two of them met for two hours at the Capital Hilton to hash out what would be next.

Neither camp released a statement afterward, but Sanders campaign said that Thursday he would give an online address.

It turned out to be the standard Sanders stump speech, with the senator repeating over and over what his campaign 'is about,' a favorite rhetorical device of his, as he encouraged his supporters to run for down-ticket positions because many decisions are made at the state or local level.

Republicans, Sanders said, have been successfully stacking these offices with their own for years.

'I have no doubt that with the energy and enthusiasm our campaign has shown that we can win significant numbers of local and state elections if people are prepared to become involved,' Sanders said.

'We need new blood in the political process and you are that new blood,' Sanders said.

He also suggested that history would look back on his movement with pride.

'My hope is that when future historians look back and describe how our country moved forward into reversing the drift toward oligarchy,' Sanders said.
