Herbalife, (HLF) the embattled nutritional supplements company, has released its second attack-video against its chief nemesis, Bill Ackman, accusing the hedge fund billionaire of enriching himself through activist campaigns that lead to massive layoffs at his targeted companies, the Fox Business Network has learned. "Billionaire Bill Ackman would like us to believe his corporate raiding has a higher purpose than mere wealth accumulation but for the tens of thousands of employees who lost their jobs because of his meddling he is probably more prince of darkness than white knight,” the video states.
