Representative Rick Renzi, a Republican from Arizona who isn’t seeking re-election, has been indicted by a federal grand jury in an alleged scheme to profit from a land deal.

Mr. Renzi, 49, who was first elected to the House in 2002, was charged along with James Sandlin, 56, a real estate investor and one of his political backers, and Andrew Beardall, 36, an attorney who had been general counsel of Mr. Renzi’s family insurance business. Messrs. Renzi and Beardall are accused of embezzling money from insurance clients to fund the lawmaker’s congressional campaign.

“Congressman Renzi misused his public office by forcing a land sale that would financially benefit himself and a business associate, and in so doing, he betrayed the trust of the citizens of Arizona,” U.S. Attorney Diane Humetewa of Phoenix said in a statement.

The Justice Department has been cracking down on public corruption, a campaign that has targeted lawmakers. Representative William Jefferson of Louisiana, a Democrat, has pleaded innocent to bribery charges, and, in 2007, former-Ohio Republican Representative Bob Ney was sentenced to 2 1/2 years in prison after pleading guilty to conspiracy and making false statements in connection with disgraced lobbyist Jack Abramoff.
