Former president Bill Clinton lashed out on Twitter this weekend refuting reports that claim Clinton Foundation donations paid for Chelsea Clinton’s wedding.

Bill Clinton tweeted,

“No Clinton Foundation funds—dedicated to Haiti or otherwise—were used to pay for Chelsea’s wedding. It’s not only untrue, it’s a personal insult to me, to Hillary, and to Chelsea and Marc.”

Attached to Bill Clinton’s tweet is a Washington Post ‘fact checker’ titled, “Did The Clinton Foundation Pay For Chelsea’s Wedding?”
