(CNN) President Donald Trump on Tuesday referred to former White House staffer Omarosa Manigault Newman as a "dog."

"When you give a crazed, crying lowlife a break, and give her a job at the White House, I guess it just didn't work out. Good work by General Kelly for quickly firing that dog!" Trump tweeted.

Manigault Newman, an African-American woman, is currently on a massive publicity tour for her explosive book.

Now, Trump insulting and name-calling anyone -- from former staffers to opponents alike -- is nothing new. Whether he is shaming "Sloppy Steve" or "loser" Michael Wolff or using one of his most famous nicknames, "Crooked Hillary," Trump applies classic bully tactics to degrade and destroy the credibility of his so-called enemies, or really anyone who doesn't drink the Trump Kool-Aid.

It's different when he attacks people of color -- because to say that the president has a rocky history with race is putting it lightly at best. And as the country is reeling from explosive racial tensions from police brutality to alt-right rallies to the anniversary of Charlottesville, Trump still has not come out and boldly denounced white supremacy or racism. And in July, a Quinnipiac poll found that while 49% of Americans say they think Trump is racist, 47% do not.
