During a gathering in Buffalo, the Queens congresswoman and socialist superstar said such conduct is "embarrassing."
"When a nominee wins, I don't try to undermine the entire political party," Ocasio-Cortez said. "You know why? Because in the grander scheme of things we are facing a very real fascist threat in this country."
The congresswoman was in the city to support the mayoral effort of fellow socialist India Walton, who secured the Democratic primary but is competing on Election Day against four-term incumbent Byron Brown, who is running as a write-in.
AOC came to Walton's defense Tuesday after state Democratic Party Chairman Jay Jacobs insisted he shouldn't have to extend his support to Democratic candidates in every case and then made a contentious comparison between Walton and David Duke, the former Ku Klux Klan leader.
"Jay Jacobs absolutely should resign over his disgusting comments comparing a Black single mother who won a historic election to David Duke," Ocasio-Cortez tweeted.
Ocasio-Cortez's Green New Deal plan is now directing the future of city pension funds, Mayor Bill de Blasio and city Comptroller Scott Stringer announced Thursday.
AOC was on hand at City Hall Thursday as the city politicians, each with less than three months left in office, pushed $8 billion in investments to her Green New Deal agenda — outlining their obligation of the Big Apple's pension investments to climate-friendly companies.
The $8 billion through 2025 amounts to a down payment toward a previously stated commitment by de Blasio for $50 billion in pension funds spent in green-minded companies.
"I want to give credit where credit is due. It took vision and it took an incredible sense of what is possible and how to push the spectrum and reset our imaginations, and we got that from a great leader," de Blasio said during his daily press briefing, before introducing AOC, who joined Hizzoner on the dais amid negotiations on President Biden's spending bill.
"Thank you so much for changing people's minds, and resetting the entire sense of the possible with the Green New Deal. It is extraordinary," the far-left Bronx-Queens Democrat said.
"What you did change debate in this country permanently and that's one of the highest callings I can imagine, to help people see a new reality," Ocasio-Cortez gushed.
On Thursday morning, the mayor and comptroller revealed a plan for three city pension funds to reach net-zero greenhouse gas emissions in their investment portfolios by 2040.
