The UK Guardian has a good wrap-up of the story so far:
Prosecutors allege Wilkes paid Cunningham, a former member of the House Appropriations Defense Subcommittee and the Permanent Select Committee on Intelligence, more than $626,000 in bribes between 2000 and 2004 to win government contracts for his companies. But it's Wilkes' links to other lawmakers, lobbyists and government officials that has dramatically expanded the case.
