A 6:30 PM PT West Coast edition of the network's evening news will air as planned, sources tell Deadline. Earlier Tuesday, an error in CBS News' Washington D.C. bureau control room literally pulled the plug on the East Coast edition, as the network tweeted about 13 minutes after the O'Donnell-hosted show was to have begun.

"CBS News experienced technical difficulties tonight that prevented the CBS Evening News from airing at 6:30 pm, ET on the CBS Television Network," CBS News said in a statement released at 5 PM PM, confirming the West Coast broadcast would still go ahead. "The issue is being resolved, and the Mountain and West Coast versions of the CBS Evening News will air during the regular time slots at 5:30 PM/6:30 PM, MT/PT," they added, with an exclusive billed interview with Facebook boss Mark Zuckerberg scheduled as the marquee item tonight.
