PHILADELPHIA — Bernie Sanders nominated Hillary Clinton for president — but that doesn’t mean he trusts her.

Speaking at a Bloomberg Politics forum Tuesday, Sanders was asked if Clinton could be trusted to enact the left-leaning Democratic Party platform.

“Sorry, I’m not going to get into the trusted or not,” he responded.

“Hillary Clinton, you know, as I just said a moment ago, [you asked me to] characterize somebody in a way I’m not going to. Hillary Clinton is a very, very intelligent person . . . I’ve known her for 25 years.”

Meanwhile, Clinton made history at the Democratic National Convention later in the day when she became the first woman to become the presidential nominee of a major US political party.

And it was Sanders who made the motion to nominate her after Clinton secured the 2,842 delegates needed to win the roll-call vote.

The convention erupted in cheers — a marked contrast to Monday when many diehard Sanders supporters booed the mere mention of Clinton’s name.

At the forum, the Vermont senator called for a thorough house cleaning at the Democratic National Committee, which was shaken last weekend by leaked ­e-mails showing it was favoring Clinton during the primaries.

“I think we need a DNC which has a very different direction. And I honestly don’t know many of the people there. But my guess is we’re going to need a new leadership, a new direction and new personnel,” Sanders said.

He insisted he holds no grudge against outgoing DNC Chair Debbie Wasserman Schultz, a Florida congresswoman who was forced to give up her party post after the e-mails became public.

But Sanders said he might campaign for her Democratic rival, Tim Canova, in the Aug. 30 primary.

Now that he has lined up with Clinton, Sanders made the rounds urging his followers to get over the primaries and get on board with the Democratic ticket.

“Our first task is to make sure Hillary Clinton is elected president,” Sanders told a breakfast of the New York delegation. “Our second task, in my view, is to continue the political revolution.”

Brooklyn’s Carmen Hulbert told The Post she’s ready to take on the second task, but not the first.

“Bernie Sanders is a much better candidate than Hillary Clinton. He wasn’t treated well by the Democratic Party. There were rigged elections. They really don’t want change” said Hulbert, 66, a retiree. “I won’t vote for Hillary Clinton. I’ll vote for [Green party candidate] Jill Stein.”

Poornima Subramanian, a 24-year-old student from Buffalo, said Sanders was “cheated out of the election.” But she offered conditional support for Clinton if she apologizes and insists on “mass resignations” at the DNC.

“If she continues to act the way she is, I absolutely won’t be supporting her,” Subramanian said.

“If she changes course, apologizes, levels with us, tries to incorporate us rather than taking a hard turn to the right, then I would be willing to consider voting for her.”
