U.S. News & World Report - Oil tycoon T. Boone Pickens, who is recovering from a series of strokes and a fall last year, said Friday that he is closing his Dallas energy-focused hedge fund after what he described as "one hell of a roller coaster ride."
Pickens rose to national prominence in the 1980s when he led a series of takeover attempts, targeting Phillips Petroleum, Unocal and Gulf Oil, among other companies.
He's also given away more than $1 billion to philanthropic causes, according to Rosser.
Pickens said in the statement that he will continue to engage in philanthropy and politics and to provide his perspective on energy and cultural issues.
He hosted a fundraising meeting of America First Action, a pro-Trump super PAC, at his ranch in October. He plans to host a summit to discuss a planned veterinary school at Texas Tech University at his ranch later his month, Rosser said.
