In a special comment on Friday's episode of "Moyers and Company," the former press secretary to President Lyndon Johnson pointed out what he believes to be at the very core of corruption in Washington, D.C.: "the revolving door" between working in government and lobbying it.

"[The] revolving door culture... that inevitably means, when push comes to shove, that corporate interests will have the upper hand in the close calls that determine public policy," Moyers said. "It's how the insiders fix the rules of the market no matter which party is in power."

He added that even though President Barack Obama implemented a series of widely praised lobbying reforms, "those rules and regulations have loopholes big enough for Santa and his sleigh to drive through, reindeer included."
