Republican Pennsylvania Senate candidate Dr. Mehmet Oz has financial ties to at least two pharmaceutical companies that supply hydroxychloroquine, an anti-malaria drug that he has floated as a possible Covid-19 treatment.

Oz, a physician and veteran television show host who is facing Democrat John Fetterman in the race for Pennsylvania's open Senate seat, owns along with his wife at least $615,000 in shares of Thermo Fisher Scientific, according to his financial disclosure. Thermo Fisher Scientific's website lists hydroxychloroquine sulfate as one of its available products. It is unclear when Oz and his wife bought the stock, or whether they owned it as Oz promoted hydroxychloroquine as a Covid treatment early in the pandemic.
