A show on these kind of news networks consist of "blocks".
Blocks are just the chunks of the show separated by the commercial breaks. They're designated by letter. A half hour show might have 3 or 4 blocks (A, B, C, D) and an hour long show could go up to F or G (or more!). How long they are depends on how long your breaks are and how many you have. Generally the A block is all your top stories, B block might be weather or a feature, same with C block. If your show is a full hour, you might do a "reset" with more hard stories in the C or D block (depending on which one falls at the :30 mark in your show).
That Gretchen dedicates two blocks to this incident indicates that she (or rather her producers, or even the network) feels it is rather important.
