Rensselaer County Sheriff Kyle Bourgault didn't send a sternly worded letter. He didn't hold a press conference. He filed a federal lawsuit — and brought fourteen of his colleagues with him.
The case is Bourgault v. Hochul, Case No. 1:26-cv-01637, filed in the Northern District of New York. Fifteen elected sheriffs against one governor. That's not a disagreement. That's a mutiny.
The target is New York's Local Cops, Local Crimes Act, which Governor Kathy Hochul signed into law and which took effect on August 25, 2026. The law bans 287(g) cooperation agreements between local law enforcement and Immigration and Customs Enforcement. Before the ban, 12 New York agencies had active 287(g) agreements. On August 25, those agreements became illegal under state law. Sheriffs who had been cooperating with federal immigration enforcement were suddenly told by Albany that doing so was no longer permitted.
The sheriffs' argument is straightforward: the state cannot prohibit county law enforcement from cooperating with federal authorities carrying out federal law. Federal law trumps state law.
While Hochul's lawyers prepare to defend the cooperation ban in court, federal agents have been demonstrating exactly why that cooperation matters. Homeland Security Secretary Markwayne Mullin announced the results of Operation Rotten Apple, a 30-day ICE sweep spanning New York City, Long Island, and the Hudson Valley that ran from July 27 through August 29.
The numbers: more than 2,100 arrests.
"Over the last 30 days Operation Rotten Apple has taken over 2100 criminals off the streets," Mullin said. "These arrests included gang members, rapists, murderers, and child predators."
Gang members. Rapists. Murderers. Child predators. Those aren't abstract policy categories. Those are the people Hochul's new law is designed to shield from local cooperation with ICE. These are the people she wants to keep roaming the streets of New York state.
New York Attorney General Letitia James has backed Hochul's position. NYC Mayor Zohran Mamdani has made sanctuary policy a centerpiece of his administration. The political alignment in Albany and City Hall is clear: federal immigration enforcement is the enemy, and any local official who assists it is acting against state policy.
The sheriffs see it differently. These are elected officials — not appointed bureaucrats, not political operatives — elected by the counties they serve. Fifteen of them looked at a law that tells them they can't cooperate with ICE to remove violent criminals from their communities and concluded that the law itself is the problem.
The timing is brutal for Hochul. Operation Rotten Apple's arrest total — 2,100 in 30 days across the regions her law now covers — arrived the same week her legal team has to mount a defense of blocking exactly that kind of operation. She has to argue in court that banning local-federal cooperation serves New York's interests while federal agents are pulling murderers and child predators off New York streets through that same cooperation.
Fifteen sheriffs, one lawsuit, 2,100 arrests, and a governor caught between her own legislation and the results it's trying to prevent. The state response is due September 9. The arrests, presumably, will continue whether Albany responds or not.
