CNBC veteran journalist Mark Haines, founding editor of "Squawk Box" and a network fixture for 22 years, died unexpectedly Tuesday evening, CNBC reported. He was 65 years old.
Haines co-anchored "Squawk on the Street," a loose, often blunt look at the financial markets.
"With his searing wit, profound insight and piercing interview style, he was a constant and trusted presence in business news for more than 20 years," CNBC president Mark Hoffman said in a statement to employees. "From the dotcom bubble to the tragic events of 9/11 to the depths of the financial crisis, Mark was always the unflappable pro.
"Mark loved CNBC and we loved him back. He will be deeply missed."
Traders at the New York Stock Exchange paused for a moment of silence.
Co-anchor Erin Burnett Burnett shared an on-air goodbye with Haines earlier this month when she left for CNN. She recalled her first day on air with Haines, saying he implored producers to "give the girl something to do here."
