David Plouffe, the architect of President Obama's 2008 presidential campaign, said there are "legitimate questions" to be asked about the function of the Clinton Foundation.

Plouffe told NBC's "Meet the Press" that questions persist about the Clinton Foundation, particularly what its function would mean if she becomes president of the United States.

"I think there's legitimate questions about the Clinton Foundation, the press is clearly spending a lot of time on that," Plouffe told NBC. "But I think if you look at both of these candidates in terms of who can you trust and some of these financial dealings, I don't think there's much of a comparison."

The former Obama adviser applauded the Clinton Foundation's decision not to shutter its doors and defended the organization's work on air.
