Longtime conservative commentator Lou Dobbs has died at age 78, former President Donald Trump announced on social media Thursday. “The Great Lou Dobbs has just passed away — A friend, and truly incredible journalist, reporter, and talent,” Trump posted on Truth Social. “He understood the world, and what was ‘happening,’ better than others.” Trump praised Dobbs as “unique in so many ways” and sent his condolences to the TV personality’s wife, Debi, and the Dobbs family. “He will be greatly missed!” Trump wrote. A short time later, an Instagram page tied to Dobbs confirmed the broadcaster’s death. “It’s with a heavy heart we announce the passing of ‘The Great Lou Dobbs,’” the message read, remembering him as a “patriot and a great American” and “a fighter till the very end.” A cause of death was not reported. The former president’s Truth Social post appeared to be the first announcement of the death of Dobbs, who spent more than 20 years at CNN and a decade at the Fox Business Network. Dobbs was a loyal Trump supporter known to promote conspiracy theories.
