Unfortunately no more info then that. According to the CNN website:
Republican Arizona Congressman Rick Renzi indicted on multiple federal charges, sources tell CNN.
www.cnn.com
And for now that's all it says.
UPDATE:
AP Has a little more:
WASHINGTON (AP) — Republican Rep. Rick Renzi has been indicted for extortion, wire fraud, money laundering and other charges related to a land deal in Arizona.
A 26-page federal indictment unsealed in Arizona accuses Renzi and two former business partners of conspiring to promote the sale of land that buyers could swap for property owned by the federal government. The sale netted one of Renzi's former partners $4.5 million.
