Did Donald Trump's racist tweets violate federal laws against workplace discrimination?

When President Trump said on Sunday that "'Progressive' Democratic Congresswomen" should "go back and help fix the totally broken and crime infested places from which they came," was he violating federal workplace discrimination law?

We aren't lawyers and we don't know, but here's something relevant from the U.S. Equal Employment Opportunity Commission website, "Immigrants' Employment Rights Under Federal Anti-Discrimination Laws" -

Ethnic slurs and other verbal or physical conduct because of nationality are illegal if they are severe or pervasive and create an intimidating, hostile or offensive working environment, interfere with work performance, or negatively affect job opportunities. Examples of potentially unlawful conduct include insults, taunting, or ethnic epithets, such as making fun of a person's foreign accent or comments like, "Go back to where you came from, " whether made by supervisors or by co-workers.

One things many minorities hear more than a few times in their lives is, "Go back to where you came from." I always responded, "What, Los Angeles?"
