He has hosted a number of events raising awareness of MS over the years, drawing praise for his efforts.

Cavuto gave an emotional sign-off to viewers at the end of his final show on the network on Thursday evening

Joking that some of his coworkers “weren’t even born” when he started his show three decades ago, he thanked “most of” his viewers for their support over the years.

He also acknowledged his ongoing health problems as his voice cracked at times during the short address.

Current and former co-workers have praised the veteran anchor in the wake of the announcement.

Howard Kurtz, a Fox News host, paid tribute to Cavuto’s long and successful media career, as well as his battles against health issues.

“He has made enormous contributions, while battling serious health problems,” he wrote on X.

“But he is also a first-class human being who is gracious to everyone, whether they are high or low on the totem pole. We will miss him!”

Fox & Friends host Janice Dean also took to X in the wake of the news, describing him as a “hero,” and saying she would “miss seeing” him in the office.

“When I was diagnosed with MS almost 20 years ago he gave me hope that I could still pursue my dreams,” she wrote.

“Always kind, generous, and an inspiration. Grateful to call him a friend.”

Sean Graf, a political adviser and presenter, wrote on X, “Love @TeamCavuto! It was an HONOR to work for him for 4 years.”

Cavuto is also a former CNBC anchor, where he hosted the channel’s Market Wrap for a number of years, and contributed to NBC News.

In recent years he was a high-profile critic of President-elect Donald Trump, facing occasional attacks from the Republican politician.

Cavuto was one of the final original Fox News stars still on the network since 1996.
