“I haven’t heard her say the things I think need to be said,” he said on “CBS This Morning.”

Sanders then articulated how Clinton could win his backing after their battle over the Democratic presidential nomination.

“I want her to say, among other things, we have a crisis in higher education,” he said. "Public universities and colleges should be tuition-free. Raise the minimum wage to $15 an hour.

“I believe that healthcare should be a right of all people. I would love for her to say that and move forward aggressively to make that happen.”

Sanders said he remains unsure if and when he could endorse Clinton’s presidential bid.

“We’re talking,” the Independent Vermont senator said. "I can’t give you that answer. It’s not just me," he said referring to his supporters.

Asked if he would back Clinton before next month’s Democratic National Convention, he said, “I would hope that that would happen, or it may not happen.”

Sanders added he launched his White House run because traditional politicians are ignoring voters.

“The establishment sometimes forgets real-live, flesh and blood people in this country are hurting and they’re hurting badly,” he said.

“The American people are unhappy. We need policies that protect working-class people. Why do so few have so much and why do so many have so little? These are the issues the establishment is going to have to deal with.”

Sanders on Friday admitted he plans on voting for Clinton during a separate interview with MSNBC.

Clinton earlier this month crossed the 2,382 delegate threshold necessary for clinching the Democratic presidential nomination.

Sanders has repeatedly refused to concede that honor, vowing his campaign will continue through next month’s convention in Philadelphia.
