Dr. Oz, running for U.S. Senate in Pennsylvania, reports at least $100 million in assets

Before he gave up his entertainment career to run for U.S. Senate, Mehmet Oz — the celebrity heart surgeon best known as the host of daytime TV's "The Dr. Oz Show" — amassed assets worth more than $100 million, including homes, stock, life insurance and connections to his in-laws' tree-trimming empire.

Oz on Wednesday night filed a financial disclosure form — required of all Senate candidates — that tallies a long list of investments that back up the finances of a man who has said he put $10 million into his campaign in Pennsylvania.

Oz valued his assets at between $104 million and $422 million, according to a tally by The Philadelphia Inquirer, a wide range that is a result of the Senate's request that each asset be valued within a certain dollar bracket. If elected, he would be one of the wealthiest members of the Senate — and possibly the wealthiest.
