Baltimore Mayor Stephanie Rawlings-Blake, also stepped in to help convention organizers at the last minute when she banged the gavel to officially begin the convention Monday. Wasserman Schultz was originally scheduled to perform the ceremonial task, but bowed out after the email controversy. 

Since the convention, Rawlings-Black has found herself in a Twitter war with Republican presidential nominee Donald J. Trump.  The two traded blows on twitter after the Baltimore Mayor sharply criticized Trump’s decision to skip the 2016 National Urban League conference. 

In a tweet, Trump called the mayor “a joke.” 

“I see where Mayor Stephanie Rawlings-Blake of Baltimore is pushing Crooked hard,” Trump tweeted. “Look at the job she has done in Baltimore. She is a joke!”

It might’ve ended there. But Sunny Hostin, a senior legal correspondent and analyst for ABC News, tweeted at the mayor, bringing Trump’s tweet to her attention.

“@realDonaldTrump is heckle tweeting my friend @MayorSRB,” Hostin wrote. “Badge of honor my friend.”

Twenty minutes later, Rawlings-Blake fired back.

“Girl bye,” she tweeted at Hostin and Trump, “if he can’t take criticism from “a joke”, what’s he gonna do when somebody real comes for him? #notready”
