Randy Mastro withdrew his nomination to be corporation counsel in a letter addressed to Mayor Eric Adams on Tuesday.

The surprise move comes after Mastro, who was the mayor’s nominee, sat through hours of tough questions from the City Council and ahead of a vote scheduled for this week that likely would have denied his bid.

In the letter, which was obtained by NY1, Mastro blamed City Council Speaker Adrienne Adams for leading what he called an “anything but fair” nomination hearing last month, and also said the council speaker set out to “deny” the mayor of his preferred pick.

Although the City Council was scheduled to vote on Sept. 12, the council speaker and a large number of the City Council’s 51 members already said they would be voting “no” on Mastro, focusing on his time as a top aide to former Mayor Rudy Giuliani.

The mayor accepted the withdrawal in a statement obtained by NY1, and also defended Mastro, arguing, “It’s unfortunate that politics has seeped into this process and, as a result, will deprive New Yorkers of one of the most qualified candidates for this office our city has ever seen. I want to thank Randy for his willingness to serve the city he loves and his time and effort over the last few months meeting with members of the City Council to discuss his transformative vision for our esteemed Law Department.”

In a statement, a City Council spokesperson wrote, in part, "While we are glad to see the unnecessary conflict and divisiveness that Randy Mastro's nomination represented come to an end, his withdrawal letter demonstrates why so many lacked trust that he would be a suitable lawyer for all city officials, rather than just for the mayor."

The move continues a months-long cold war between the mayor and the City Council. It’s also unclear who he will tap as replacement for former corporation council Sylvia Hinds-Radix, who resigned in June.
