McCaul’s wealth exploded in 2010, making him the richest member of Congress by tens of millions of dollars.
Most of the four-term House Republican’s wealth comes from his relatives: father-in-law Lowry Mays founded one of the country’s most profitable radio broadcasting companies, Clear Channel Communications. All of the lawmaker’s assets are either attributed to his spouse, Linda, or a dependent child, according to his 2010 financial disclosure form.
Linda McCaul also has an interest in Laguna Water Company, a water distribution company, and a real estate partnership, both based in San Antonio, Texas, and both worth at least $100,000.
McCaul reported no liabilities for 2010.
