Donald Trump and New York City Mayor Bill de Blasio are continuing their war of words.

De Blasio on Monday criticized Trump’s recent remarks to a Jewish group for allegedly fostering harmful stereotypes.

He also, during an interview on CNN, ripped the Republican presidential candidate’s plan to list the nation’s Muslims in a database.

The Democrat said Trump’s rhetoric was “doing the bidding of our enemies.”

Trump hit back on Twitter a short time later.

He said de Blasio was “the worst mayor in the United States.” Trump says he has watched New York, where he has a home, suffer from dirty streets, homelessness and crime.

He called the state of the city a “disgrace.”
