Bill Clinton admitted Monday that some Clinton Foundation donors might have given money to the charity in the hopes of getting official favors.

“Well, since we had more than 300,000 donors, it would be unusual if nobody did [try to get favors],” Clinton told NPR in an interview.

“Maybe some of them gave money for that reason [to gain influence],” he said, “but most of them gave it because they liked what we were doing.”

The Clinton Foundation relied on the State Department to weed out possible conflicts of interest and the favor-seekers would be out of luck, the former president added.

“It was natural for people who’ve been our political allies and personal friends to call and ask for things,” he said. “And I trusted the State Department wouldn’t do anything they shouldn’t do, from a meeting to a favor.”

Of course, Clinton’s wife, Hillary Clinton, was the secretary of state — the head of the State Department — during the time in question.

Both the State Department and the Clinton Foundation have been under fire for giving special access to donors.

The ex-president gave the interview on the occasion of the Clinton Global Initiative annual meeting, which kicked off its session Monday in Midtown.

It’ll be the final CGI meeting — and Bill Clinton has even pledged to remove himself from the Clinton Foundation board if his wife becomes president.

Hillary Clinton herself is skipping CGI, as is another frequent guest, President Obama.

Bill Clinton also claimed that people who voted for him but who are having doubts about his wife have been influenced by a constant stream of negative press.

“This email thing was treated like the most important event since the end of World War II,” he said.
