Rep. Alexandria Ocasio-Cortez of New York said Wednesday that Mayor Eric Adams should resign amid intensifying federal corruption investigations, becoming the first member of Congress and the most prominent Democrat to call on the mayor to step down.

Ocasio-Cortez, a progressive who has criticized Adams over budget cuts and policing, said she didn’t see how he could “continue to govern” and that the “flood of layoffs and vacancies is a threat” to the functioning of government.

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

Ocasio-Cortez initially gave 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 has come under increasing scrutiny. The probes have resulted in a flurry of subpoenas and search warrants that have created a growing crisis at City Hall.

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

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

In perhaps an even more troubling sign for the mayor, Sen. John Liu released a statement Tuesday criticizing Adams after news broke that Banks planned to retire at the end of this year.

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

“For anyone who smugly claims that people accused of serious crimes should not be in jail to now say that New York City’s second black mayor should resign based on rumors and innuendo — without bringing a single charge — is the height of hypocrisy,” the mayor said in a statement. “I run this city to protect it from exactly that kind of false politics. The people of this city elected me to fight for them, and I will stay and fight, no matter what.”

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