Murtha's brother is a lobbyist for some defense industries and has steered defense contracts their way...like over $20 million in just one year (2004). Murtha is the ranking democrat on the Defense appropriations subcommittee. He used to be the Chair of it.
The Hill reported in October that John Murtha is the top House recipient of campaign contributions from the defense industry for the past three years. As of the October 31, 2005 Federal Election Commission report, Murtha had received over $200,000 from defense firms in the 2006 election cycle, surpassing the next highest recipient by over $60,000. You can read more on this @ Murtha CYA
Yes he is trying to inoculate himself from ending up like Duke Cunningham.
If a genuine war hero goes down for bribery and contract shenanigans (AS HE SHOULD !!!) then even more so should a posturing war hero wannabe !(Now left-whining POS!)
