Will Trump stick to his speech on Tuesday evening?

On Tuesday evening, President Trump will address the nation on TV to make the case for the government shutdown/the wall. Undoubtedly, his aides will have prepared a speech for him.

Do you think he'll stick to the speech or will he start winging it at some point?

Update 3: Moved it back from "Pregnancy"
