Starting his career in radio before moving to television, he became a key figure at CNN, where he hosted Moneyline beginning in 1980. His work in business journalism helped define him as a trusted voice in the industry. However, his views on various topics, including immigration, led to controversies, and he left CNN in 2009. He later joined Fox Business, where Lou Dobbs Tonight became a major program until its cancellation in 2021.
Fox News Media also honored him in a statement, recognizing his contributions to broadcasting and his impact on cable news. He is survived by his wife, Debi, and their six children, leaving behind a legacy of bold reporting and public debate.
