More than 100 GNP lawmakers occupied the National Assembly main chamber for the second consecutive day on Friday in a last-ditch attempt to block the passage of an impeachment motion that may jeopardize their front-running presidential candidate Lee Myung-bak in next week's election, Yonhap News Agency reported.
