At the height of Moreland madness, two of the most high profile players in this seemingly never-ending saga – US Attorney Preet Bharara and state Attorney General Eric Schneiderman – met for a very public lunch in lower Manhattan yesterday, multiple sources confirm.

The Democratic duo was spotted lunching at City Hall Restaurant – an eatery favored by members of the New York City political set due to its proximity to (you guessed it) City Hall. Schneiderman and Bharara have known each other in a professional capacity for the past several years, but aren’t personal friends, according to a source familiar with their relationship.

It’s worth noting that Bharara, who is investigating the demise of Gov. Andrew Cuomo’s now-defunct corruption-busting Moreland Commission, would probably not be seen in such a public place with Schneiderman if the attorney general was a target of that probe.

Given the role that Schneiderman played, however, through his agreement to deputize its 25 members to broaden their purview beyond the executive branch and loaning of top aides to staff the commissinon, it’s possible that he is providing information to the US attorney as the investigation progresses.

Schneiderman has been under fire – especially from his Republican opponent, former Pataki administration official John Cahill – for refusing to comment on the Moreland Commission and explain why he did not speak up when the Cuomo administration was, as has been exhaustively documented by the New York Times (and refuted by Cuomo himself) interfering with its work.

It’s no secret that the relationship between Cuomo and Schneiderman has been rocky, dating at least as far back as the 2010 Democratic primary to replace Cuomo in the AG’s office.

At the time, Cuomo was widely believed to prefer Nassau County District Attorney Kathleen Rice to Schneiderman in that race, due in part to her ticket-balancing capability (the Democratic slate that year was all white, almost all male – with the exception of US Sen. Kirsten Gillibrand – and all from downstate), but also because he felt Schneiderman was too liberal and, as a former senator, too tied to the scandal-scarred Legislature.

Now Rice is running for the seat of retiring Long Island Rep. Carolyn McCarthy, and is trying to keep a low profile given her role as one of the Moreland Commission’s three co-chairs. (Unlike Onondaga County DA Bill Fitzpatrick, whose public comments have provided considerable cover for Cuomo in the wake of the Times story, neither Rice nor the third co-chair, Milton L. Williams, Jr., have offered support of the governor’s position).

Rice may soon be forced to end her silence. Tomorrow, her Republican opponent in the NY-4 race, former Nassau County Legislator Bruce Blakeman, is holding a press conference tomorrow afternoon outside the Nassau County Supreme Court in Mineola to “to discuss his opponent’s role in the Moreland Commission and answer questions from the media.”
