"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.

Prosecutors said DeLay, a Texas Republican who once held the No. 2 job in the U.S. House of Representatives, used his political action committee to illegally channel $190,000 in corporate donations into 2002 Texas legislative races through a money swap.

DeLay, who appeared on Dancing with the Stars last year, said he did nothing wrong.
