Sanders spokesman Michael Briggs would not confirm reports of a scheduled endorsement, telling USA TODAY: "We are continuing to have conversations with Secretary Clinton's campaign and look forward to reaching a result that everybody's happy with. Sen".
Clearly, some of Senator Sanders' supporters will not vote for Hillary Clinton regardless of what she does or says. Clinton's campaign outlined plans earlier this week to expand college affordability and place a three-month moratorium on student loan payments, a proposal that was developed with the Sanders campaign.
The policy is also a win for Sanders, who campaigned on a platform to make tuition free at public colleges and universities. For Bernie Sanders, a campaign that began as a liberal crusade will probably end that way, with the Vermont senator still fighting for the issues that made up his political revolution even as his clout fades.
Sanders and Clinton have come out against the trade deal, but President Barack Obama supports it. Clinton supporters said they believed that toughening the trade language made enough of a statement without directly opposing the president.
The New York Times also alluded to Clinton meeting Sanders halfway on universal healthcare by supporting a "public option" in addition to the Affordable Care Act.
Sanders met with House Democrats Wednesday during which he was reportedly booed for failing to endorse Clinton.
Sanders' fights are not fully finished - he sought more platform changes at a party meeting in Orlando that started Friday - but he appears to be winding down this period of figuring out his direction. In our poll, almost half of Sanders voters (46 percent) have an unfavorable opinion of Hillary Clinton while 94 percent of Clinton voters hold a favorable opinion.
Sanders hopes to push Clinton more to the left, particularly insisting "that the Democratic Party becomes a party that represents working people, not Wall Street". While he has hung back, other party leaders have coalesced around Clinton.
Though Clinton has the support of many older Democratic voters, Sanders was able to capture the interest and fiery spirit of many young liberals.
He'll likely speak at the Democratic National Convention later this month, though it's unclear how involved he'll be in helping Clinton afterwards on the campaign trail.
"I had the impression that we live in a democratic society", Sanders said, adding that while he respects the president "he's not right all of the time". While Sanders notched wins in smaller states (he ultimately won 23 states), she cleaned up in the delegate-rich contests.
In his speech, Sanders discussed the importance of transforming America through social and political reform.
