From 2008:
The family of Joe Biden, who was the vice presidential candidate of the DEMOCRAT Party's 'reform Washington' ticket with Barack Obama, appears to have been enmeshed in the same D.C. money game that Obama denounced.
One of the senator's sons -- Hunter, a Washington lobbyist -- and the senator's brother, James --received a $1 million investment in their purchase of a hedge fund company from the senator's largest political donor, an Illinois law firm, SimmonsCooper.
At about the same time, the firm also steered dozens of asbestos litigation cases to a Delaware law firm where the senator's late son, Beau, worked before moving on to become attorney general of the state of Delaware. Beau Biden was credited with acquiring the Illinois client for his firm whose long time managing partner described himself as a "Biden family friend".
The DEMOCRATS' vice presidential candidate, who was a senator in Washington since 1972 when Obama was 11 years old, claimed he did not know about any of the sons' or brother's business dealings with the law firm, whose representatives lobbied his office in the past.
