Ingrid Lewis-Martin, Mayor Adams’ top advisor and confidante, has resigned from City Hall. Her last day is Sunday, Fabien Levy, Deputy Mayor for Communications, said. “Ingrid has not been just a friend, a confidant, and trusted advisor, but also a sister,” Mayor Adams said in a statement. “We’ve always talked about when this day would come, and while we’ve long planned for it, it is still hard to know that Ingrid won’t be right next door every day. I, and every New Yorker, owe her a debt of gratitude for her decades of service to our city.” Mayor Eric Adams next to his Chief Advisor, Ingrid Lewis-Martin at City Hall on June 11. (Luiz C.

It also comes as Adams is headed into a a battle for reelection and a trial for his five-count federal indictment in April. In a statement, Lewis-Martin thanked Adams and said she is retiring and will focus on her family. “I thank you for seeing in me things that I did not see in myself,” she wrote. “I extend humble gratitude to you for encouraging me to be my authentic self and for having my back during some trying times. As you would say, this has been a good ride; I will use author’s license and say that this has been an amazing ride.” Luiz C.

In the appearance on Arthur Aidala’s show, Lewis-Martin said she believes the public will see “we have not done anything illegal to the magnitude or scale that requires the federal government and the DA’s office to investigate us,” a comment that angered the mayor as it intimated there might have been some criminal activity, according to the sources. One of the sources said the mayor and Lewis-Martin hadn’t spoken in weeks prior to Sunday’s announcement.
