It’s no secret that CNN makes schedule changes with no official announcement. Increasingly, Twitter is where you need to go to get any pertinent information.
During the MH370 fiasco, Early Start started “earlier” at 4am. And since then, it has started at 4am, with no indication how long it will last.
The Twitter account for the show was recently updated to reflect the show’s new start time. Whether that means it will be permanent now, or if they just updated the account bio to reflect the current start times, is anyone’s guess.
