Two of North Carolina's delegation are among the 15 richest.
Hayes, a Concord Republican, comes in at No. 10. That's down four spots from last year's survey, in part because he suffered considerable financial losses, though he's still worth $36.1 million.
He reported owning between $500,001 and $1 million in Altria stock; another $500,001 or more in timber investments and at least $2 million worth of property in Minnesota and South Carolina. He also holds at least $3 million in municipal bonds and a personal debt of $1 million for his plane.
Dole, a Salisbury Republican, comes in at No. 14. Her $16.1 million portfolio includes a 1 percent stake — worth more than $1 million — that her husband, former Sen. Bob Dole, has in a family trust. She also owns roughly $2 million in promissory notes.
In addition, Dole has collected more than $1 million in rent from a 119-acre property in Kansas and has multiple hedge funds and trust accounts worth more than $1 million each.
The rankings are based on financial disclosure forms filed by the politicians.
