Biography Jang was born in Goheung County, South Jeolla Province. He started his political career under former president Kim Dae-jung. He was elected to the National Assembly as a member of the Millennium Democratic Party in 2000 but lost in 2002 due to his violation of election law.

Controversy While he was working at Jang Sung-min's Current Affairs Tank, he was involved in controversies about reporting that the Gwangju Uprising was supported by North Korea. Although he denied it, the controversy was taken seriously. Because of that, he was forced to create a new party with the name of Grand National Unity Party.
