U.S. Rep. Thomas Petri is among the richest members of Wisconsin's congressional delegation.
According to his financial-disclosure forms, the Republican from Fond du Lac is worth between $9.5 million and $40.5 million.
His most valuable asset is his stock in Walgreen Co., which is worth between $5 million and $25 million. He also lists three other assets worth at least $1 million apiece.
No other Wisconsin congressman listed total assets worth more than $9.3 million, although Reps. James Sensenbrenner and Sean Duffy were granted extensions and hadn't filed their reports as of Thursday.
Members of Congress have to release annual reports listing their assets, liabilities and stock transactions. However, they're only required to list the value of their assets in broad ranges, making specific comparisons difficult.
