ARI MELBER (HOST): Since the election, caravan coverage has mostly disappeared. The same folks hyping this before the election aren't even talking about it now. Here was Trump before Election Day.

...

Fox News echoing that message with almost breathless self-parody.

...

Since the election, Fox News had 33 hours of segments about the caravan through Election Day and since the election, you see it right there, nothing on Election Day. The hours of coverage melt away. And I want to be clear, the facts here are important and they don't only indict Fox News. Let's follow them where they lead. Two of the most respected print outlets in America, The New York Times and The Washington Post, ran a whopping 84 stories on the caravan in the single week before the election and that fell, you see it there, to half in just the week after. Now, the drop off shows how much this non-troversy was echoed by serious outlets.

...

Now, all of that is important so people don't get played again. We can learn together but the joke may be on Trump who lost the election, even with that caravan coverage. But it's also on those of us in the media and Stephen Colbert hit the punch line about how the caravans completely disappeared after the election.
