Lee was elected to the
Legislative Yuan in 2001 via the
People First Party proportional representation party list. In 2004, he was named a defendant in two court cases, as
Chen Che-nan and
Chang Ching-fang separately charged Lee with libel. Later that year, Lee offered to resign his legislative seat, as PFP chairman
James Soong attempted to join the body and engage President
Chen Shui-bian in debate. After Lee's first term expired, he was nominated by the People First Party to join the
National Communications Commission. In 2011, Lee was again placed on the party list ballot as a PFP legislative candidate. During his second legislative term, Lee served as caucus whip for the People First Party. In November 2012, he attended a student-led protest against the monopolization of
media in Taiwan. Lee opposed the 2013 passage of the Senior Secondary Education Act and Junior College Act because he believed that the laws did not allocate enough money to the
education system. After the
2014 Kaohsiung gas explosions, Lee proposed special statues that would help relief efforts. In 2015,
Chen Yi-chieh,
Kao Chin Su-mei,
Hsu Hsin-ying, and Lee founded a new legislative caucus named the New Alliance. ==Political stances==
