Andrew Ross Sorkin is the latest addition to CNBC’s morning line-up. The New York Times columnist and DealBook founder should already be familiar with the job as the new co-host of “Squawk Box,” since he’s been a frequent guest host recently. Sorkin is also the author of Too Big to Fail, an award-winning best-seller on the financial crisis and Washington’s response. Joining fellow co-hosts Becky Quick and Joe Kernen, Sorkin’s new role will beginning on on Monday, but he will continue to contribute to the New York Times, where he writes about mergers and acquisitions.
