The IRS has launched an investigation into the Clinton Foundation’s possible “pay to play” activities, after 64 GOP lawmakers demanded it.

In an interview with “Fox and Friends Weekend,” Peter Schweizer, the author of “Clinton Cash,” explained the crux of the investigation.

“There are international anti-bribery standards that say bribing a public official can mean giving them money, giving their family money or giving their charity money,” he told Fox’s Tucker Carlson. “Just because it’s a charity doesn’t mean it’s not important or not interesting. It constitutes bribery every bit as much as if somebody’s putting money in somebody’s pocket for a benefit.”

Schweizer said the Foundation has yet to disclose more than 1,100 foreign sources that contributed to the organization.

But, he believes, as usual, the Clinton’s will get away unscathed for political reasons.

“There’s real questions about the political motivations of the IRS,” he said. “The IRS is looking at this because essentially they have to. 60 members of Congress have said, ‘We want you to look into this.’ That doesn’t mean they’re going to do a thorough, aggressive or fair job.”
