Rep. Alexandria Ocasio-Cortez of New York on Wednesday called for Mayor Eric Adams to resign amid mounting federal corruption investigations, becoming the first member of Congress and the most prominent Democrat to call on the mayor to resign.

Ocasio-Cortez, a progressive who has criticized Adams over budget cuts and policing, said she could not imagine him “continuing to govern,” adding that the “flood of resignations and vacancies” threatened the ability of the government to function.

“The ongoing investigations will make it impossible to recruit and retain a qualified administration,” she said on X. “For the good of the city, he should resign.”

Ocasio-Cortez initially addressed the statement to the New York Times, which first reported the news.

As Adams faces at least four separate federal investigations into his 2021 campaign fundraising and several members of his administration, his ability to lead the city is increasingly being questioned. The investigations have resulted in a barrage of subpoenas and search warrants that have sparked a growing crisis at City Hall.

On Tuesday, Schools Chancellor David Banks became the latest top official to announce his retirement from the administration. NYPD Commissioner Edward Caban and the mayor’s chief counsel Lisa Zornberg both resigned abruptly earlier this month. And Ashwin Vasan, the city’s health commissioner, said Monday he plans to step down early next year.

Ocasio-Cortez, who represents parts of Queens and the Bronx, joins a small group of left-leaning elected officials who have recently called for Adams’ resignation. They include City Councilwoman Tiffany Cabán and State Senator Gustavo Rivera.

Perhaps an even more worrying sign for the mayor was the fact that State Senator John Liu issued a critical statement about Adams on Tuesday after it was announced that Banks planned to retire at the end of the year.

Liu, a mainstream Democrat who supported Adams in the 2021 general election, said the schools chancellor’s resignation came at the “worst possible time,” adding that the “sudden and unexpected announcement raises questions about the continued viability of this mayoralty.”

“When someone who self-righteously claims that people accused of serious crimes should not be in prison now says, based on rumors and insinuations, that New York’s second black mayor should resign – without a single charge being filed – that is the height of hypocrisy,” the mayor said in a statement. “I lead this city to protect it from exactly this kind of sham politics. The people of this city elected me to fight for them, and I will stay and fight no matter what.”

When asked on Tuesday where he saw himself in a year, the mayor replied, “I see myself raising my right hand again and being called mayor of the city of New York.”
