Lou Dobbs Tonight is an American editorial commentary and discussion program hosted by Lou Dobbs, which previously broadcast on CNN and currently is broadcast on the Fox Business Network. The hour-long show aired live on evenings every weekday, and was replayed in the overnight/early morning hours. It covered the major news stories of the day with a focus on politics and economics. Field correspondents provided additional reporting and occasionally served as guest anchors. During Dobbs' tenure, notable politicians and economists were often guests on the show, facing his often pointed questioning. On November 11, 2009, Dobbs announced that he would be leaving CNN effective immediately. CNN anchor John King replaced the outgoing Dobbs beginning on March 22, 2010 with his new show John King, USA. Dobbs was eventually hired by Fox Business Network, which re-launched Lou Dobbs Tonight in March 2011.
