When Sean Hannity said he was talking to Michael Cohen about real estate, many people rolled their eyes.

But it turns out the Fox News host does have vast real estate holdings, worth at least $90 million, according to reporting in The Guardian.

Hannity has said that he hates investing in the stock market, and instead buys real estate. But no one had reported the scale of investments by the host, who makes about $30 million a year. Hannity's shell companies have spent at least $90 million buying up at least 870 homes spread over seven states, the Guardian reported.

Among the holdings are mansions and apartment buildings rented to low-income families.

Troublingly given how Hannity talked about the raid on Cohen's office and homes without disclosing that he was a client, Hannity also has dealings journalist would normally disclose.

He bashed Obama about the foreclosure rate but bought up homes during the crisis, the report says, and he made deals involving the US Department for Housing and Urban Development which he did not disclose when interviewing and praising Ben Carson, who Trump appointed to lead the department.
