AUSTIN, Texas - Former U.S. House Majority Leader Tom DeLay - once one of the most powerful and feared Republicans in Congress - was convicted Wednesday on charges he illegally funneled corporate money to Texas candidates in 2002.

Jurors deliberated for 19 hours before returning guilty verdicts against DeLay on charges of money laundering and conspiracy to commit money laundering. He faces up to life in prison on the money laundering charge.

After the verdicts were read, DeLay hugged his daughter, Danielle, and his wife, Christine. His lead attorney, Dick DeGuerin, said they planned to appeal the verdict.

"This is an abuse of power. It's a miscarriage of justice, and I still maintain that I am innocent. The criminalization of politics undermines our very system and I'm very disappointed in the outcome," DeLay told reporters outside the courtroom. He remains free on bond, and his sentencing was tentatively set to begin on Dec. 20.

Prosecutors said DeLay, who once held the No. 2 job in the House of Representatives and whose heavy-handed style earned him the nickname "the Hammer," used his political action committee to illegally channel $190,000 in corporate donations into 2002 Texas legislative races through a money swap.

DeLay and his attorneys maintained the former Houston-area congressman did nothing wrong as no corporate funds went to Texas candidates and the money swap was legal.

The verdict came after a three-week trial in which prosecutors presented more than 30 witnesses and volumes of e-mails and other documents. DeLay's attorneys presented five witnesses.

Prosecutors said DeLay conspired with two associates, John Colyandro and Jim Ellis, to use his Texas-based PAC to send $190,000 in corporate money to an arm of the Washington-based Republican National Committee, or RNC. The RNC then sent the same amount to seven Texas House candidates. Under Texas law, corporate money can't go directly to political campaigns.

Prosecutors claim the money helped Republicans take control of the Texas House. That enabled the GOP majority to push through a Delay-engineered congressional redistricting plan that sent more Texas Republicans to Congress in 2004 - and strengthened DeLay's political power.

DeLay's attorneys argued the money swap resulted in the seven candidates getting donations from individuals, which they could legally use in Texas.

They also said DeLay only lent his name to the PAC and had little involvement in how it was run. Prosecutors, who presented mostly circumstantial evidence, didn't prove he committed a crime, they said.

DeLay has chosen to have Senior Judge Pat Priest sentence him. He faces five years to life in prison on the money laundering charge and two to 20 years on the conspiracy charge. He also would be eligible for probation.

The 2005 criminal charges in Texas, as well as a separate federal investigation of DeLay's ties to disgraced former lobbyist Jack Abramoff, ended his 22-year political career representing suburban Houston. The Justice Department probe into DeLay's ties to Abramoff ended without any charges filed against DeLay.

Ellis and Colyandro, who face lesser charges, will be tried later.

Except for a 2009 appearance on ABC's hit television show "Dancing With the Stars," DeLay has been out of the spotlight since resigning from Congress in 2006. He now runs a consulting firm based in the Houston suburb of Sugar Land.
