Since he's not a fan of being Politically Correct, it's no surprise that Donald has only used the term "African American" 14 times in the last 7 years. And all those 14 times has been since 2012. I'm sure Donald has his own term he uses instead of African American.
Trump tweets have used the word "thug/thugs" 21 times.
Trump tweets have used the word "Mexico/Mexican" 145 times.
He's used the word "Loser" way too many times.
Check Donald out for yourself. Do a Twitter search using from:@realDonaldTrump then whatever keyword you'd like to check.
