In the aftermath of the coverage of the Boston bombing, CNN continues to tweak its lineup.
A few astute viewers may have noticed that Wolf Blitzer has been filling in on “CNN Newsroom” for the last week or so at 1 PM, a few hours ahead of “The Situation Room” at 5 PM. Jake Tapper and Brooke Baldwin have also filled in on the early afternoon hours.
The move is not believed to be permanent, just an experiment tied to some major breaking news events, like the Bush Library dedication, president Obama’s news conference and developments in the bombing case. As with the “AC360″ format tweak though, if it works, it could very will stick around.
