Bill Clinton on Sunday acknowledged that some of the donors to the Clinton Foundation likely made those donations in order to influence foreign policy, when Hillary Clinton led the State Department.

But in a Sunday interview with NPR, Clinton insisted that the donations never influenced policy.

"Well, since we had more 300,000 donors, it would be unusual if nobody did," Clinton said when asked if some of the donors might have been trying to ingratiate themselves with the Clintons. But he added, "The names I saw in the paper, none of them surprised me and all of them could have gotten their own meeting with Hillary."

"When you've been doing this kind of work as long as we have, you know the people who are the major players," he said. "And also, some of them who call my staff, people were doing double duty back then, and I had an office of the former president when it was natural for people who had been our political allies and personal friends to call and ask for things."

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

Clinton said he also "trusted the State Department wouldn't do anything they shouldn't do, from a meeting to a favor."

The Clinton Global Initiative, which is part of the Clinton Foundation, has its final gathering this week. Bill Clinton has promised to step away from CGI, which he started after his presidency, should his wife be elected.

"I've had this job longer than I ever had any job, and I've loved it," Clinton said. "And you know, we always say in response to our critics, that nobody in my family ever took a penny out of this foundation and put millions of dollars in. But I would have paid more to do this job. It was the most fun thing I've ever done."

Clinton also criticized the media for negatively covering Hillary's ongoing email scandal.

"They're responding to the fact that this email thing was treated like the most important event since the end of World War II. I wonder if there's a man in America that could have taken what she's been through in the last year and a half," he said.
