Sign Language

I was watching the Governor speaking about the aftermath of the storm. There was a sign language interpreter on the side. I don't understand why they are wasting money on sign language interpreters when they can use the money for storm recovery. Is it to show they are politically correct? Wouldn't it be better to have close captioning? Not all people that have a hard time hearing or are deaf can understand sign language.

Let me know what your thoughts are about this please!
