New York City's school chancellor announced Friday that he is resigning, citing the coronavirus pandemic's personal toll on his family. Chancellor Richard Carranza, who has spent three years in the job, said he has lost 11 family members and friends to the virus and needed time to grieve. Carranza will be replaced by Meisha Porter, an executive superintendent who oversees school districts in the Bronx. She would be the first Black woman to lead the school system.
