A Senate Democrat accused his colleagues from the Empire State of being "spinless" for not endorsing New York City Democratic mayoral nominee Zohran Mamdani.Sen. Chris Van Hollen, D-Md., did not name names but still railed against New York Democrats for not backing Mamdani, whose brand of politics has shaken the Democratic Party since his primary victory earlier this year.And those New Yorkers who havent thrown their support behind Mamdani happen to be the most powerful Democrats in Congress: Senate Minority Leader Chuck Schumer, D-N.Y., and House Minority Leader Hakeem Jeffries, D-N.Y.SOCIALIST CANDIDATE MAMDANI MEETS WITH NY DEMS AS THEY WITHHOLD ENDORSEMENTS"Many Democratic members of the Senate and the House representing New York have stayed on the sidelines," Van Hollen said during an event in Iowa on Saturday. "That kind of spineless politics is what people are sick of. They need to get behind him and get behind him now."Neither Schumer nor Jeffries, both natives of Brooklyn, have endorsed Mamdani, despite having met with him a handful of times in recent weeks amid growing pressure from congressional Democrats to throw their weight behind him.Van Hollen also went after the Democratic Party as a whole, arguing, "Weve become a party that too often trims its sails.""Too cautious, too rudderless," he said. "Too attached to poll-washed, pundit-rinsed, and donor-dried messages. What comes out of the wash is all bleached and blow-dried."TOP HOUSE DEM SIDES WITH MAMDANI CRITICS ON KEY CONTROVERSY SURROUNDING HIS CAMPAIGN: 'LEGITIMATE ISSUE'A spokesperson for Jeffries fired back at Van Hollen in a statement to The New York Times."Leader Hakeem Jeffries will have more to say about the general election well in advance of Nov. 4," said Jeffries spokesperson Justin Chermol. "Meanwhile, confused New Yorkers are asking themselves the question: Chris Van Who?"Schumer met with him last week and told reporters that it went well."We had a good meeting," Schumer said. "We know each other well, and were going to keep talking."Since Van Hollens remarks, Democratic New York Gov. Kathy Hochul threw her support behind the self-described democratic socialist, and she gave her rationale behind her endorsement in a New York Times opinion piece on Sunday.She noted that though they disagreed on many items, they found common ground on affordability and safety issues in the city. And in Mamdani, Hochul said she saw a mayoral hopeful who would not "surrender one inch to President Trump."MAMDANI'S FAR-LEFT ALLIES AIM TO PRIMARY HAKEEM JEFFRIES AND OTHER NYC HOUSE DEMOCRATS"Mr. Mamdani and I dont see eye to eye on everything, and I dont expect us to," she said. "I will always reserve the right to disagree honestly and to argue passionately. But I also believe that New York State and New York City are at our best when we stand together against those who attempt to tear us apart."Fox News Digital reached out to Schumer and Jeffries for comment but did not immediately hear back.
