He is one of the core leaders of the National United Front of Democracy Against Dictatorship (UDD), also known as the "Red Shirts", and a former Member of Parliament of the Pheu Thai Party.

[2] In the May 1992 pro-democracy uprising after government troops secured the area around Phan Fa Bridge and the Democracy Monument, Jatuporn joined protest leaders in demonstrations at Ramkhamhaeng University, eventually resulting in military-backed Prime Minister Suchinda Kraprayoon's resignation on 24 May 1992.

Jatuporn moved to the Pheu Thai Party and retained his seat as an MP and became one of the core leaders of the pro-Thaksin National United Front of Democracy Against Dictatorship (UDD), commonly known as the "Red Shirts".

[3] Jatuporn, along with Nisit Sinthuprai, was jailed on terrorism charges for alleged involvement in the shooting of Army Major General "Seh Daeng" Khattiya Sawasdipol,[4] after bail was denied on 12 May 2011.

[5] However, when the House of Representatives was convoked, the Election Commission (EC) ignored this and endorsed Jatuporn's status as a party list MP,[6] and he was released on bail on 2 August 2011.
