First, he said that it "felt like the people at the Gap knew about the school shooting that Matthew McConaughey was talking about before it even happened", comparing it to the movie _The Truman Show_. In response to Carlson's request for clarification he does say "I'm not saying that they did" but he clearly doesn't rule it out, either.

Second, it's not clear what statement by The Gap he's talking about, but my guess is that this is related to the delayed launch of his product line:

The "coordinated message" here appears to be "it is bad that children were killed".
