Congressional Democrats on the House Oversight Committee are asking New York City to provide additional information about conditions at Rikers Island, arguing there is no justification for keeping the data confidential.

In a letter to the Mayor’s Office of Criminal Justice, the lawmakers — led by Chairwoman Carolyn Maloney of New York — criticized an apparent agreement between the city and the federal monitor overseeing Rikers to file a “confidential one-time supplement” containing information requested by the Legal Aid Society about the conditions at the troubled jail complex.

Nineteen detainees at city jails or recently released from city jails have died so far this year on Rikers Island and at other facilities.

“The agreement will deprive stakeholders of valuable and timely information about the true state of affairs at Rikers, thwarting public accountability and efforts to correct urgent problems and prevent more unnecessary deaths,” the lawmakers wrote.

Bronx and Queens Rep. Alexandria Ocasio-Cortez and Maryland Rep. Jamie Raskin signed the letter along with Maloney.

In addition to the supplemental report, the lawmakers are requesting data on the numbers of self-harm events, overdoses, use-of-force incidents and disciplinary cases against staff. They also want information about the median length of stay for incarcerated individuals at Rikers, plus staffing levels.

“The City’s decision to withhold this information is troubling in light of recent press reports detailing Commissioner Louis Molina’s potential misuse of compassionate release to manipulate official death counts at Rikers,” they wrote. “We request the immediate production of this information to the Committee.”

In September 2021, the House Oversight panel began reviewing the situation at Rikers, speaking with the teams of mayors Bill de Blasio and Eric Adams, the Board of Correction — the city jails system’s oversight authority — the city’s district attorneys, and advocates.

The letter was sent less than two weeks before the end of the current Congress, when the House — including the oversight panel — will change hands to Republican control. Maloney is also about to leave Congress, after losing a primary against fellow New York Democrat Rep. Jerry Nadler.

Separately, last year, all Democratic members of the New York City congressional delegation called for President Joe Biden to intervene at the jail.
