Everybody pronounces it shaa. The only ones I ever heard pronounce it Cher were actors faking a bad Cajun accent.
I thought it was a hilarious, did you see the reply tweets to it. Its pretty funny stuff. And I am not sure why they just wouldn't come out and just say it was a typo and then he went to bed. But instead I think they said what they said because they like to fuck with the media. And since it was all anyone could talk about, they lied as they usually do. And are probably giggling like children about it. But hey that's our President... Making America a big joke.
Many Trump fans are now applauding the Orange Idiot for his coded meaning.... apparently some troll reported on the internet somewhere that covfefe means "I will stand up" in Arabic.... so what Trump REALLY meant was "Despite the negative press I will stand up". Simply genius, right? Now, why he couldn't just say that in his regular sixth grade English, or why he chose Arabic... they don't bother with those questions. Nor do they bother with checking out the veracity of that language claim in the first place... turns out covfefe doesn't mean that at all.
