Renzi, a Republican, represented Arizona’s sprawling 1st Congressional District from early 2003 until early 2009. He chose not to run for re-election in 2008 while facing the federal indictment. He was charged with 32 felony counts.
His trial began May 7. The jury reached a verdict Tuesday after about four days of deliberations.
The panel found Renzi guilty on 17 of the 32 counts against him, including wire fraud, conspiracy and extortion. He was acquitted on the remaining counts which included similar charges but on different dates.
Renzi left the courthouse without commenting.
“We are pleased that the jury acquitted Mr. Renzi on 15 counts,” his defense attorney, Chris Niewoehner, said in a statement. “We are disappointed by every guilty verdict. We will continue to fight these charges, including on appeal.”
The U.S. Attorney’s Office did not immediately have a comment.
The indictment charged that Renzi, while in office in 2005, held hostage possible parcel swaps involving public land proposed as the site for an Arizona copper mine unless it included purchasing private land owned by a former Renzi business associate, James Sandlin.
According to the indictment, an investment group agreed to pay $4.6 million for the associate’s land, and he then paid Renzi $733,000 for his help.
Sandlin had owed Renzi money from past business dealings involving land in Kingman, authorities said. It wasn’t immediately known what verdicts were rendered against Sandlin.
Charges in the other part of the case accused Renzi of embezzling more than $400,000 in premiums from his family insurance business to fund his 2002 campaign for Congress.
Renzi had pleaded not guilty to all charges.
Two other co-defendants, who both had worked for Renzi’s insurance agency and were charged only in that part of the case, have already faced trial. One was acquitted, while the other was convicted on some charges only to later have them overturned on appeal.
