Warner recorded substantial gains in 2011, with his wealth rising more than $9 million.
The former Virginia governor saw many of his assets rise in value last year. For example, an investment fund with Hound Partners, based in New York City, went from at least $1 million in value in 2010 to $5 million last year.
Warner had a successful business career before entering politics. The senator has experience in venture capital and was an early investor in Nextel.
The Virginia Democrat reported one liability for 2011: a loan guarantee from Virginia Commerce Bank worth at least $15,000.
