Where was the Aircraft Carrier Task Force?

Just weeks before 9/11/2012 the defense department moved the aircraft carrier group, normally stationed in the Mediteranean, to the Persian Gulf to take part in mine sweeping exercises.  This taskforce was how we kept the no-fly zone over Libya.  It would have been able to provide close-in support for the folks in Benghazi.  Wouldn't it have been better to delay the exercises until after the anniversary of 9/11?
