Former Taiwan First Lady Wu Shu-bian admitted in court on Monday laundering charges of $2.2 million and forging documents.

Wu said she sent the money overseas after she received it from a contractor working on a government construction project. However, she said she did not steal the money or accepted bribes, which makes it appear that the money was a political donation.

The former first lady apologized for having involved family members, whom she maintained were innocent. Her husband, former President Chen Shui-bian, was arrested in 2008 over money laundering, bribery and embezzlement accusations, which he denied.

Their son, Chen Chih-chung, and his wife had previously pleaded guilty to money laundering charges. The same guilty plea was entered by Wu's brother.

Lawsuits are not new to Wu. In 2006 she was acquitted of accepting vouchers from the Sogo department stores in exchange for her intervention on behalf of the store.
