Hillary Clinton flew into a furious rage when she was blindsided by last month's media coverage of horndog hubby Bill's massive payoffs to support an alleged former mistress' business, RadarOnline.com can exclusively reveal.
"Hill was foaming at the mouth, when she had to read about it instead of hearing it from Bill first!" one Clinton family insider claims.
The presidential candidate, who is embroiled in a tooth-and-nail campaign battle with Republican nominee Donald Trump, was caught short by the humiliating news that the Clinton Global Initiative forked over a staggering $2 million to a for-profit company run by Bill's alleged former mistress, Julie Tauber McMahon!
"With just months to go before Election Day, this shady 'donation' by the foundation couldn't have come to light at a worse time for Hillary," the source says.
The former First Lady's world-class temper was on full display after the story broke nationally in May, according to shocked campaign insiders.
"Her face went red with rage and she called Bill in full view of several staffers, screaming at him into the phone," said the source. "She called him a brainless, sex-obsessed idiot and when she was finished, she hurled the phone against the wall!"
Sources say she also demanded Bill provide her with his daily itinerary the night before and agree to having one of her staffers travel with him to monitor his moves.
McMahon, 56, was instrumental in having the former President make the massive commitment to the Energy Pioneer Solutions company, in which she has a 29 percent ownership stake.
"It's highly doubtful that Bill would have given the company a second look if Julie wasn't on board."
Bill first pursued McMahon after Hillary was elected U.S. Senator from New York in 2000 and traveled to Washington, D.C., for weeks at a time.
The buxom blonde was a neighbor who lived near the Clinton family home in Chappaqua, New York, and was nicknamed "The Energizer" by his Secret Service detail after frequent clandestine visits to their estate.
Now insiders reveal that Clinton never intended to tell his wife about the shady contribution.
"He intended to cover it up permanently because of Julie's involvement and, he thought he'd get away with it," the source claims.
Clinton staffers even tried to bury the financial commitment and scrub it from the agenda at the Global Initiative's 2010 financial conference.
It was only restored after multiple media inquiries were made about it.
"The main reason it was buried was to avoid calling attention to Bill's cozy relationship with Julie," according to another source.
McMahon, a divorcee with three kids, told reporters that she didn't know how the financial commitment to her company came about, and that she wasn't involved, but insiders say Hillary wasn't buying it.
"Hill's suspicions of Julie all along have now been confirmed and turned to rage that Bill's gotten into bed with her on this business venture — and now having it come out as she's fighting for her political life," a shocked source alleges.
Now insiders say the contribution may result in a Federal probe by the IRS because tax-exempt foundation money is not allowed to be donated to a for-profit business.
Even worse — the investigation could uncover embarrassing details of Bill's relationship with Julie.
"This is a monumental mess and the timing is disastrous for Hillary," says the source.
