I got those numbers last night from opensecrets.org. I did multiple searches for contributions by IndyMac and its senior executives to any political committees or candidates, and found none. I also checked with the Clerk of the House website and IndyMac is not registered as a lobbying organization or as a client of any lobbyist.
I may be putting 2 and 2 together and getting 5 here, but it looks damn fishy to me.
