We haven't been able to use the fan for a fortnight

He's referring to the phrase "When the shit hits the fan". The senator mentions in the interview that the last time he made speculative comment about the issue he wasn't able to use the fan for a while. This, presumably, is because when he made the comments last time so much shit hit the fan that he wasn't able to use it for a fortnight.

No one likes a shitty fan.
