I just went and looked at another website that has teh speech in question, and commentators are saying Trump didn’t use the P-word at all. He probably mouthed it, at worst. Going to watch the whole speech just now and find out :)
This week's talking points issued to the media by the DNC/GOP joint task force state that Trump should be depicted as using vulgar language all the time, thus making him unpresidential.
Next week they'll go after him for having bought real furs for his women (because he hates women... according to week 12 talking points).
