Taiwan's former first lady Wu Shu-chen has pleaded guilty to forgery and money-laundering.
At a pre-trial hearing into her corruption case Tuesday, the wheelchair-bound Wu admitted laundering money abroad, but denied charges of embezzling money from a special presidential fund.
Authorities have jailed her husband, Chen Shui-bian on suspicion of embezzlement, money laundering, taking bribes and forgery. He denies the allegations, but has acknowledged that his wife sent $20 million in excess campaign funds to overseas bank accounts.
Authorities suspect the funds were illicit. Taiwan law allows candidates to retain unused political donations.
Mr. Chen has said the corruption allegations against him and his family are politically-motivated. He has accused his successor, President Ma Ying-jeou, of pursuing the case to appease China. Mr. Ma denies that accusation.
