DeLay's attorneys were to begin presenting their defense on Wednesday.
During 10 days of testimony spread over nearly three weeks, prosecutors presented 33 witnesses and volumes of e-mails and other documents in their efforts to prove allegations that DeLay's political action committee illegally channeled $190,000 in corporate donations into Texas legislative races in 2002 through a money swap.
DeLay, who has denied wrongdoing, maintains no corporate money went to Texas candidates and he had little involvement in how the PAC was run.
The former Houston-area congressman is charged with money laundering and conspiracy to commit money laundering. He faces up to life in prison if convicted.
