Assembly Speaker Carl Heastie on Wednesday endorsed New York City Public Advocate Tish James for attorney general, giving her another major endorsement of a top Democrat as the party meets for the first day of its convention at Hofstra University.

“Public Advocate Tish James is an incredible leader and a champion for New Yorkers from every walk of life,” Heastie said in a statement. “That’s why I was proud to be one of Tish’s earliest supporters when she was seeking to become New York City’s Public Advocate, because I believe all citizens deserve a strong voice in our government.”

James is among three Democrats seeking the AG nomination. The Legislature on Tuesday appointed Barbara Underwood, who had been serving in an acting capacity, to fill out the remainder of Eric Schneiderman’s term.

“For years, Speaker Carl Heastie has been a great leader in New York and it is an honor to receive his endorsement,” James said. “I look forward to continuing to work with Speaker Heastie to help New Yorkers from the Bronx to Buffalo and in every corner of our great state. As our Attorney General, I will be committed to protecting the rights of every single New Yorker and making sure our working families have a watchdog in government who is always looking out for them.”
