Joseph Ai-guo

 (Chinese: 昌愛國; pinyin: Chāng àiguó; born July 17, 1946) is a retired Tsengian politician and military officer. A former member of the National Prosperity Party (NPP), Ai-guo served as the 13th President of Tseng from 1996 to 2004. He was involved in the 2008 Tsengian constitutional crisis and was expelled from the NPP as a result.

Bio
Also known as Chang Ai-guo, he was born in Hillsborough on Tseng's birthdate, July 17, 1946. Ai-guo joined the Tseng Armed Forces in 1964, and served in the army. During the Long Summer of 1966-67, Ai-guo arrested 6 people and killed 1, which he admitted to in 2001. In 1987, he was honorably discharged from the military with a rank of colonel.

Ai-guo entered politics after his discharge and became a leading figure of the ruling NPP. He was against Julius Han's "radical" policies. He became NPP chairman following Han's presidency, and was elected president in 1996. He reversed some Han-era policies, but kept some, like the 40 hour work week. Ai-guo was re-elected in 2000.

Involvement in the crisis
In early 2008, it was revealed that president James Huang and his administration had accepted bribes. Adult tapes of politicians (including Ai-guo) were also discovered. Huang refused to resign, sparking a constitutional crisis. There were protests, and eventually Huang resigned. Tseng's foreign affairs minister, and Ai-guo's daughter, Eliza Chang, also resigned. On June 1, 2008, Huang, along with several other politicians (including Ai-guo) were expelled from the NPP, their reputations destroyed.
