CNBC Staple Mark Haines Dead At 65

Longtime CNBC fixture Mark Haines — the founding anchor of the cable net’s morning show Squawk Box — died unexpectedly Tuesday night. He was 65.

The cause of death is unknown.

“With his searing wit, profound insight and piercing interview style, he was a constant and trusted presence in business news,” said CNBC president Mark Hoffman in a statement. “He was the unflappable pro. He loved CNBC and we loved him back. He will be deeply missed.”

Haines launched Squawk Box in 1995, six years after joining the then-nascent cable network. In 2005 he became co-anchor of CNBC’s Squawk on the Street with Erin Burnett, who’s now at CNN.

Haines is survived by his wife, Cindy, and his two children, Matt and Meredith.
