I spent this morning at the polls talking to voters about the @NYWFP slate of candidates with Deputy State Director Cori Marquis! I voted on the WFP ballot line, and I encourage you to do the same—voting on the WFP line is critical to protect their ballot line for the future!
Happy first weekend of early voting! I had a great time yesterday chatting with AD-66’s first midterm voters at polling sites around the district, and I’ll be out at the polls all week. You can vote early any time between now and Nov 1st, or on Election Day, Nov 3rd!

🎉🐴 IT’S OFFICIAL: ROMANCH’S LAW HAS PASSED! 🐴🎉
Today, the @NYCCouncil voted to END horse-drawn carriages in New York City. 🗳️✅
After DECADES of fighting, failed bills, and too many lives lost, New York has finally said: no more. 💪
Here’s what Romanch’s Law does:
🚫 No new carriage licenses, starting now
🐎 Carriages off NYC streets by June 1, 2028
🤝 A transition plan for carriage workers
THANK YOU to @SpeakerMenin @juliemenin, Council Member @chrismartenyc, Council Member @harveyforny, Health Chair @lynn4nyc Schulman, Majority Leader @shaunabreu, Council Member @shahanafrombk, Council Member @ShirleyAldebol, the Animal Welfare Caucus, every co-sponsor and Council Member who voted YES, and @nycmayor Mamdani for committing to sign Intro 943 into law. 🙌
And thank YOU. Every email, every call, every rally. You made this happen. 📣
This is what political power for animals looks like. 🔥
Next stop: Mayor Mamdani’s signature. ✍️
I was so glad to rally at City Hall today to celebrate that we finally passed Romanch’s Law, banning horse carriages in Central Park. The horse carriage industry has consistently engaged in cruel and dangerous practices for too long, and I’m particularly grateful (1/2)
to @JulieMenin and Chris Marte for keeping humans and horses in New York safe (2/2)
Last week I got to meet with @NYUDems, attend disability pride in Union Square and chat with 504 Democratic Club, join the festivities at La Mama’s block party, co-host a fundraiser for @VittoriaNYC, attend a GVSHP plaque unveiling, and explore open artist studios in @Westbeth !

I’ve been lucky enough to have worked with @DIDNYC for over a decade. DID is a true grassroots organization who understands and passionately fights for the lower Manhattan community. I’m so excited to go into the general election with their endorsement!
I had a great time yesterday in NY-17, knocking doors for @CaitforNewYork, Joe Rand, and Patrick Carroll with @villagedems, @ebottcher, @LindaBRosenthal , @VanessaAronson , @allenroskoff , and so many more Manhattan Democrats! (1/3)
If you have any time before Election Day, I strongly encourage you to join a @votebluenyc bus and knock some doors in a swing district! I know firsthand how much every vote matters—and an extra shift of canvassing could be the difference in any of these critical races (2/3)

This Indigenous Peoples' Day, I was proud to join the Canadian Consul General and representatives of the Lenape Nation for a gift of two maple trees by the Canadian government, to be planted in City Hall Park. It goes without saying that our President has made this a rough (1/2)
I was proud to speak at @TishJames’s debate watch party tonight, and I meant what I said: Tish James is one of a very small number of people keeping our country as together as possible, and we would all be so much worse off without her work

This afternoon in Marble Hill, a New Yorker was shot by an ICE agent in a residential neighborhood. Early reports indicate agents surrounded him and a 5-year-old child in his car before firing multiple rounds. We believe the child was physically unharmed.
This is an unconscionable and incredibly serious situation. I have called the President; when we speak I will demand that he ends all ICE enforcement actions in our city. I will not stand by while ICE agents terrorize our communities.
Our thoughts are with the injured New Yorker and his family tonight. We are praying for his recovery.
Get ICE out of our neighborhoods. Get ICE out of our hospitals. Get ICE off our streets. Get ICE away from our children.
Abolish ICE.
I was proud to stand with @spocuaw yesterday as they rallied for a fair contract!
