The wealth of Dr. Mehmet Oz, the celebrity heart surgeon nominated by President Donald Trump to lead CMS, has swelled in part from for-profit health care companies over which he'd wield significant power if confirmed, according to a newly filed government ethics report. In the filing, the 64-year-old former talk show host pledged to divest from those companies within three months of confirmation and said that until then, he wouldn't participate in any matter that could affect his investments. Oz's net worth is between $98 million and $332 million, according to an analysis of the disclosure, which lists asset values in ranges but does not give precise dollar figures. Oz shot to fame and made millions off his daytime talk show. His most recent disclosure shows he also holds millions of dollars worth of shares in health insurance, fertility, pharmaceutical and vitamin companies.
