Modeling Journey

CNBC Anchor Mark Haines passed away at the age of 65. He was the consummate professional, unflappable, tough and deeply smart. "We all know Mark as being the toughest guy around on the guests," Cramer said. "He was the standard. He was the former host of the CNBC shows Squawk Box and Squawk on the Street (which airs from 9-11am ET).

He was a  "building block" of the network, CNBC President Mark Hoffman said. "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... Hanies' former co-anchor Erin Burnett called "a fearless".

Co-host Erin Burnett moved on to CNN, with May 6th, 2011 being her last show with Haines. He said in a statement, "Mark’s legacy is that he didn’t tolerate any B.S. from anyone. He wanted to tell the story -- and that’s why so many viewers trusted him. He would always ask the question that nobody else would ask. He was fearless."

"If Mark Haines is interviewing God this morning, he's giving him the Devil," tweeted Dan Davison. CNBC President Mark Hoffman said Haines was "always the unflappable pro."
