Elorza, a Democrat, said Thursday he also told Fung, a Republican, that Kevin Aherne no longer works for the city.
Aherne was a communications director in Providence's planning department. Screenshots posted on Twitter, including one by Fung , show a Tuesday tweet in which Aherne accuses Fung and Cranston police of criminalizing poverty, adding a crude play on words with the mayor's name.
The tweet showed an officer apparently speaking to panhandlers, but Aherne mistook a Warwick cruiser for one from Cranston.
Aherne deleted his Twitter account and confirmed to WPRI-TV he was resigning over the tweet, but declined to discuss it further.
Fung tweeted to Elorza that it wasn't a Cranston cruiser, with #HeardBetterSlamsFromA5thGrader.
