Tucker Carlson famously reads his scripts directly from a teleprompter, so the fact that the following screw up made it on the air means (1) some writer needed to misread the date of Janet Yellen’s quote as 2007; (2) some video archivist finding the clip filed under the proper year, 2017; (3) a script supervisor or producer approving the video and script; and (4) Tucker Carlson himself reading the script and thinking it all fits together.
But then you go on air, and your on-air producer sees the “2017” bug in the corner and whispers in your ear, “We totally fucked up. This piece makes no sense. She said that in 2017, not before Bush’s Great Recession in 2007 like you just said.” And a normal host would be embarrassed. But thankfully, we’re talking about Tucker Carlson, who can feel no shame.
