Andrew Cuomo was jeered by protesters when he showed up unannounced Thursday at a fundraiser for a breakaway group of Senate Democrats that he supposedly dissolved last week.

The dustup, outside the New Leaf restaurant in Fort Tryon Park, was caught on video and gave opponent Cynthia Nixon fodder to attack.

“They say a picture is worth a thousand words. Well, this evening’s video just says five: Andrew Cuomo cannot quit Republicans,” Nixon said after footage of the governor’s cameo circulated on Twitter.

The Independent Democratic Conference’s seven-year split from mainline Democrats had kept Republicans in power in the Senate. The governor and the rogue group announced last week that it would reunite with fellow Democrats and dissolve the separate faction.​

“Gov. Cuomo looked New Yorkers in the eye last week and claimed he was finally stopping his support of the group that handed Republicans control of the senate,” Nixon said. “And then tonight, he was caught on camera going back on his word, and secretly attending a fundraiser for them.”

Critics of the incumbent governor claimed that the division between mainline Democrats and the IDC increased Cuomo’s stronghold over the legislature.

Members of the breakaway group held the fundraiser as they are still clinging to their separate campaign account to fend off challenges from Democrats who are furious the IDC voted with the GOP as Trump and his agenda ascended to the White House.

Protesters bashed the group for continuing to fundraise as a separate entity and targeted Cuomo as he walked into their Upper Manhattan fundraiser.

“You will never be President!” Shame! Shame! Shame,” one protester shouted.

Though long-planned as an event for the breakaway group, Cuomo’s campaign insisted the fundraiser was​ “​for Democratic unity,” and included at least two mainline Democrats also running for election: Shelley Mayer and Luis Sepulveda.

“This was a Senate Democratic fundraiser supporting Democratic unity and attended by both Luis Sepulveda and Shelly Mayer,” said spokesoman Abbey Fashouer. “The IDC has disbanded and Senate Democrats are united and after nearly a decade of turmoil anyone trying to divide that does so only to the betterment of Republicans. The Governor is 100 percent focused on maintaining a unified Democratic Party to fight Trump in Washington, take back the House and the State Senate.”
