Sen. Claire McCaskill's last financial disclosure statement showed income of at least $2.27 million in 2007, not counting her Senate salary.

McCaskill — who called Friday for limiting pay at companies bailed out by the government to $400,000, what the president makes — could have earned, at the top end, more than $9.4 million in 2007, the disclosure shows.

The disclosure (attached below) lists a range of incomes from dozens of investments, most of them involving McCaskill's husband, Joe Shepard.

(UPDATE: It's clear from some of the responses below that not everyone is familiar with Shepard's businesses. For many years he used state-issued tax credits and other assistance to build and maintain housing in the state and across the country.

Those tax breaks and credits were a cost to the state treasury — taxpayers. Here's how the Post-Dispatch reported in 2006: “The picture of Shepard that emerges from public records and interviews reveals a shrewd businessman who has aggressively sought public subsidies and made millions, mainly in rural, low-income housing.” Or the AP, in 2004: “Joseph Shepard has built millions of dollars worth of low-income housing projects with the help of low interest loans and tax credits from the Missouri Housing Development Commission.”)

It is not possible, using the disclosure, to set a firm top end on McCaskill's family income, since one investment (Missouri Tax Credit Fund LP) provided income of “$1,000,001 /Over”.

But using the lowest possible income value for each investment, the family received at least $2,274,335 in the calendar year.

The income does not include the value of the underlying investments, only the income provided in 2007.

Open Secrets — which tracks congressional fundraising and campaign spending — says McCaskill is worth between $20.4 million and $44.4 million.

As a Senator, according to the Congressional Research Service, McCaskill earns $169,300.
