This link does not have video of the actual broadcast, so don't use it as a reference. The "X" lasted only 3 frames, but the "X" on the video at this site smoothly fades in and out. It is "fake but accurate".
I hope everyone is not using the clip at this site as proof - the clip is bogus.

I disagree. Watch the Political Teen clip carefully, and also watch the crawl at the bottom of the screen. You will see that the appearance and disappearance of the black X exactly corresponds with the updating of the crawl text in which the text at one position is replaced by the same text at a position slightly to the left. If that video clip is fake, it's a damn good job.
The X was generated by the same equipment which generate the crawl text. The only question is whether there was a legitimate equipment failure/glitch, an operator screw-up, or a deliberate action.
