Story summary

On the 25th anniversary of the September 11 attacks, New York City's first Muslim mayor, Zohran Mamdani, faces controversy over his decision to attend memorial events despite calls from some victims' families and former Mayor Rudy Giuliani for him to stay away. Mamdani, who lost an older brother in the attacks, insists on honoring those affected by reading out names at Ground Zero. Meanwhile, nearly 110,000 signatures have been collected through a petition urging Mamdani not to attend, citing concerns over his past associations and appointments that some see as conflicting with the solemnity of the event. Despite this opposition, Mamdani is moving forward with plans to release more than 170,000 pages of documents related to air quality around Ground Zero in the months following 9/11, aiming to provide transparency on what the city knew about toxic conditions and how they handled it.

🔮 A House Democrat is asking congressional appropriators for guardrails that would prevent President Donald Trump from exploiting a loophole in federal law to buy the East Potomac Golf Course that he's been pushing to renovate with taxpyer funds.
🔮 I'm frustrated that I got it in the middle of the night, but I'm much more concerned that it's filed on the public record." The assistant U.S. attorney in the hearing, John Borchert, struggled repeatedly as Faruqui asked him to explain the government's conduct, which the judge said was unlike any case he had ever seen in the history of D.C.'s district court. Faruqui ultimately granted the request from Flores' and Benavides' attorneys to strike the amended complaint from the docket and said he would continue Tuesday's hearing to determine whether prosecutors established probable cause in their initial complaint filed last week. "Why today on this one case have you changed the entire history of how you charge cases?" Faruqui asked of Borchert.
🔮 She could not immediately be reached for comment on Tuesday.
🔮 Unglesbee said he knew recipients of white powder letters 'took it serious and would have 'hazmat come in white suits' because 'anthrax is dangerous.'
🔮 The Justice Department is asking election officials in Washington state to set aside hundreds of ballots it says may belong to noncitizen voters, the latest move by the Trump administration to intervene in a state-run election just days before the midterms.
🔮 A federal judge has ordered a top Department of Justice official back into court after President Donald Trump posted on his social media account affirming that East Potomac Golf Course will close Nov. 15 for renovations — directly contradicting repeated assertions from administration officials in a hearing last week.
🔮 The report lays out a series of warning behaviors and signs that are typical for those who might carry out targeted workplace violence, like a 22-year-old service member who "experienced multiple stressors, including chronic pain resulting from a motorcycle accident, the ailing health of a loved one, harassment from peers, and numerous reprimands and citations at work due to poor performance and tardiness," before carrying out an attack that killed two on base and injured a third person.
🔮 In a follow-up post resharing the letter, Trump wrote "They will all go to jail for a long period of time!!!"
🔮 We will continue to monitor developments closely as the facts become clear.
🔮 After initially saying they would post the sensitive information, the group told reporters they recanted the threat.
