No, because they release a fair amount of terror related information on a regular basis.
You're redefining your premise. The premise was always, in the past, that the WH would announce a new terror threat and/or raise the alert status when the poll numbers were down, not that they would release "terror-related" information.
Simply put, neither the WH nor polls had anything to do with this.
You can take off your tinfoil hat, there's no conspiracy this week.
