"Even though hate speech — speech that expresses hatred for people, as opposed to hatred for ideas — stings and hurts, it is constitutionally protected," Napolitano, a frequent Trump critic, wrote in a Fox News opinion piece published Thursday. "But when the hate speech comes from a shameless president, we have a problem."

"It implicates a racial or nativist superiority: We were here before you; this is our land, not yours; get out," he wrote. "Nativist hatred is an implication of moral or even legal superiority that has no constitutional justification in American government."

In a previous opinion piece this week, Napolitano called Trump's attack "racist."

The president's use of "go back" is a "dog whistle to groups around the country that hatred is back in fashion and is acceptable to articulate publicly," Napolitano wrote Thursday. "'Go back' is a rejection of the nation as a melting pot; a condemnation of one of America's founding values — E Pluribus Unum (Out of many, one)."
