Alex Weprin of TVNewser:

Thomas Roberts was slated to interview the National Organization for Marriage’s Maggie Gallagher, but the camera feed showed an empty chair, with Roberts saying that Gallagher didn’t show up (h/t Inside Cable News).

There was just one big, glaring problem: Gallagher was ready to appear, but was in a different studio.

ICN took issue with how Roberts handled the situation:

The proper way to handle it is to say that a guest was scheduled to appear but couldn’t make it in time and we hope they will appear in the future. Then you move on and don’t refer to it again. Given that you don’t know what actually happened you must err on the side of caution…for reasons that now seem all too obvious given that it was MSNBC booking that screwed up.
