NYC Mayor Bill de Blasio Says Donald Trump Is 'of Course' a 'Racist' De Blasio endorsed Hillary Clinton for president in October.

 -- New York City Mayor Bill de Blasio tweeted that Donald Trump, the Big Apple real estate mogul and GOP frontrunner, "behaves like a racist, speaks like a racist" and is "of course" a "racist."

Trump has drawn criticism for his remarks about Mexicans early in his campaign, in which he called them "rapists" as well as calling for a temporary ban on Muslims entering the United States.

Most recently, he sparked controversy when he appeared to dodge questions about support former KKK grand wizard David Duke during a CNN interview. Trump disavowed the KKK and Duke on other occasions though.

Trump has previously said "I'm the least racist person" and during an interview with CBS, he said "hate groups are not for me."

De Blasio continued his series of tweets by quoting John Legend's tweet Friday that called the GOP frontrunner a racist.

De Blasio then called for a "better democracy" through an "actual re-distribution of wealth" that includes a tax on the wealthy and a reform on Wall Street.

De Blasio endorsed Hillary Clinton for president in October.
