CNBC Anchor Mark Haines Dies Suddenly at 65

Veteran business journalist Mark Haines died Tuesday evening unexpectedly at the age of 65, CNBC said.

Known for his blunt and often confrontational style, Haines was an original member of CNBC after joining the cable network in 1989.

“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 released to employees, CNBC.com reported. "From the dotcom bubble to the tragic events of 9/11 to the depths of the financial crisis, Mark was always the unflappable pro.”

CNBC announced his death after the markets opened on Wednesday. The network reported he died at home, but did not disclose a cause of death.

He cut his chops in journalism as a local reporter, serving as a news anchor in Philadelphia, New York and Providence before working at CNBC. Haines also had a law degree from the University of Pennsylvania Law School and was a member of the New Jersey State Bar.

Haines was a frequent sight at the New York Stock Exchange, co-anchoring CNBC’s “Squawk on the Street” program on weekdays from 9 a.m. ET until 11 a.m. ET.

"Mark loved CNBC and we loved him back. He will be deeply missed,” Hoffman said.
