“Stephanie Rawlings-Blake was an innovative leader for Baltimore and a strong advocate for Americans in cities across the country as president of the U.S. Conference of Mayors – and we’ve worked together to address important issues in this election, like protecting communities from gun violence,” Bloomberg said in a statement.

Rawlings-Blake returned the love.

“I am proud to endorse Mike Bloomberg for president of the United States. Mike has been a good friend and mentor to me for many years,” Rawlings-Blake wrote in a prepared statement, according to WBAL TV. “He is a no-nonsense leader who has taken on the country’s toughest fights. When we were both in office, we worked together to get illegal guns off the streets of Baltimore, New York, and cities across America. He continues to lead the national movement for gun safety, building grass-roots support and working to elect candidates fighting for common sense gun safety laws. I’m excited to join Mike’s campaign and do everything I can to help elect the best candidate to defeat Donald Trump and unite our country.”
