A Growing Web of Political Abuse, Developer Debt, and Illegal Coordination
A newly filed lawsuit in Westchester Supreme Court adds weight to what many Mount Vernon residents have long suspected—Mayor Shawyn Patterson-Howard is deeply involved in a political operation powered by misused public resources, unethical campaign tactics, and a shadowy PAC known as Rise Up Mount Vernon, funded by developer interests. This lawsuit not only corroborates key allegations but also strengthens Black Westchester’s ongoing investigation into how Rise Up Mount Vernon is influencing local elections and governance behind closed doors.
The 22-page complaint, filed on June 23, 2025, by Mount Vernon resident and taxpayer Gabriel Thompson, details alleged violations of city ethics rules, state election laws, and the Public Officers Law. Among the most alarming revelations: the Mayor’s direct coordination with Rise Up Mount Vernon, which the lawsuit now documents with concrete evidence—including campaign texts, public endorsements, and shared communications infrastructure.

One critical detail now comes into focus:
Rise Up Mount Vernon was not registered with the New York State Board of Elections until May 16, 2025—just four days before the May 20th School Board election.
Despite that, the group appears to have been active well before that date—sending political mailers, promoting specific candidates, and organizing smear campaigns—all in coordination with the Mayor’s office. Under New York Election Law, no political committee may raise or spend money to influence an election prior to official registration. If Rise Up engaged in any activity before May 16, that could constitute serious violations of campaign finance and election law, including unreported expenditures, illegal coordination, and operating as an unregistered committee.
The lawsuit further alleges that Mayor Shawyn Patterson-Howard engaged in potentially unlawful conduct when she personally alerted a close associate of a school board candidate—later arrested and charged with sexually abusing a minor—of pending allegations before informing law enforcement. According to the complaint, the Mayor received a message regarding the individual’s alleged misconduct involving a 14-year-old girl and possible financial theft from a nonprofit. Rather than treating the matter with immediate urgency by reporting it to the proper authorities, Mayor Patterson-Howard allegedly summoned the accused to City Hall and disclosed the content of the anonymous warning. The individual was subsequently arrested by the Westchester County District Attorney’s Office. The lawsuit claims this action demonstrates not only a serious lapse in judgment but also a possible attempt to interfere in a criminal investigation—particularly troubling given that the accused was romantically involved with one of the Mayor’s endorsed school board candidates.
Now that the lawsuit provides clear evidence of the Mayor’s direct ties to Rise Up, the legal implications multiply. This is no longer a matter of political perception—it’s a matter of potential criminal exposure. Under state law:
- Coordinating with a PAC while in public office and using city resources to advance partisan outcomes could violate Public Officers Law § 74(3)(h) and Election Law § 17-158.
- The Mayor’s use of active-duty police officers as a personal campaign security detail—without budgetary authorization—may constitute theft of services and violation of the city charter.
- The creation and promotion of fraudulent “sample ballots” tied to the Mayor’s endorsements, distributed via a PAC not yet registered, raises questions of deliberate election interference.
This mounting evidence also casts a glaring spotlight on Kenny Plummer, a political figure widely associated with Rise Up Mount Vernon. According to a Facebook post from Candidates Andre Wallace and Nicholas Mastrogiorgio, Plummer has doubled down, actively defending the PAC’s role, asserting influence over its political narrative, and even threatening candidates.
Plummer’s judgment is further questioned by his financial entanglement with PMP Lending LLC, a developer-connected firm. A UCC filing with the Westchester County Clerk confirms that Plummer entered into a sweeping mortgage agreement that gives the lender control over income generated from the property, along with other rights. Simply put, Plummer is compromised, owing significant money to a developer in a city where development policy is now intertwined with campaign politics.
Further complicating the picture, formal complaints have been filed alleging that Kenny Plummer is illegally holding a District Leader position while no longer residing at his registered address in Mount Vernon. As a District Leader, Plummer influences who the Mount Vernon Democratic City Committee endorses in local elections. These complaints raise serious concerns about voter fraud, political eligibility, and the legal integrity of party leadership.
The lawsuit further alleges that Mayor Patterson-Howard and Rise Up Mount Vernon:
- Created and distributed partisan mailers disguised as official city communications
- Used taxpayer-funded police for political escort duties
- Hosted online forums for endorsed candidates
- Launched a smear website to discredit opponents just days before the primary
All of this points to a dangerous blurring of lines between government, campaign activity, and private special interests. If these claims are substantiated, Rise Up Mount Vernon did more than violate paperwork deadlines—it hijacked local elections under the cover of legitimacy, shielded by silence from other elected officials.
Now that there’s documented coordination between the Mayor and Rise Up, several key outcomes are possible:
- The New York State Board of Elections Enforcement Division may launch a full investigation
- The Attorney General or District Attorney could pursue charges for misuse of public resources or illegal campaign coordination
- Other candidates backed by Rise Up may now be vulnerable to ethics complaints or financial scrutiny
Mayor Shawyn Patterson-Howard said the lawsuit is frivolous and politically motivated.
“This is a politically motivated and frivolous lawsuit filed by a so-called activist. Unfortunately, it will force the City to divert valuable resources at a time when we are focused on public safety, economic development, and housing for our residents. It seeks to drag Mount Vernon back to an era we’ve worked hard to move beyond. When I took office, I promised to lead with integrity and not to do anything that would embarrass our community—and I have kept that promise. We will allow this matter to play out in court,” Mayor SPH shared with Black Westchester.
