Well that's a bit of unintended irony! I didn't see her in the stands or on the Jumbotron, didn't know she was there till I saw this in Jets Gallery.
I guess she was doing the NY rounds after meeting President Obama in Washington and doing the Today show earlier this week, last stop Jets game on Thanskgiving. Looks like she wasn't impressed either by the Jets' performance on Thursday. This could become the iconic image for this game.
