The man accused of fatally shooting the CEO of UnitedHealthcare pleaded not guilty on Monday to state murder and terror charges while his attorney complained that comments coming from New York’s mayor would make it tough to receive a fair trial.

Luigi Mangione, 26, was shackled and seated in a Manhattan court when he leaned over to a microphone to enter his plea. The Manhattan district attorney charged him last week with multiple counts of murder, including murder as an act of terrorism.

Mangione’s initial appearance in New York’s state trial court was preempted by federal prosecutors bringing their own charges over the shooting. The federal charges could carry the possibility of the death penalty, while the maximum sentence for the state charges is life in prison without parole.

Prosecutors have said the two cases will proceed on parallel tracks, with the state charges expected to go to trial first. One of Mangione’s attorneys told a judge that the “warring jurisdictions” had turned Mangione into a “human ping-pong ball” and that New York City Mayor Eric Adams and other government officials had made him a political pawn, robbing him of his rights as a defendant and tainting the jury pool.

“I am very concerned about my client’s right to a fair trial,” lawyer Karen Friedman Agnifilo said.

Adams and Police Commissioner Jessica Tisch stood among a throng of heavily armed officers last Thursday when Mangione was flown to a Manhattan heliport and escorted up a pier after being extradited from Pennsylvania.

Friedman Agnifilo said police turned Mangione’s return to New York into a choreographed spectacle. She called out Adams’ comment to a local TV station that he wanted to be there to look “him in the eye and say, ‘you carried out this terroristic act in my city.’”

“He was on display for everyone to see in the biggest stage perp walk I’ve ever seen in my career. It was absolutely unnecessary,” she said.

She also accused federal and state prosecutors of advancing conflicting legal theories, calling their approach confusing and highly unusual.

In a statement, Adams spokesperson Kayla Mamelak Altus wrote: “Critics can say all they want, but showing up to support our law enforcement and sending the message to New Yorkers that violence and vitriol have no place in our city is who Mayor Eric Adams is to his core.”

“The cold-blooded assassination of Brian Thompson — a father of two — and the terror it infused on the streets of New York City for days has since been sickeningly glorified, shining a spotlight on the darkest corners of the internet,” Mamelak Altus said.

State trial court Judge Gregory Carro said he has little control over what happens outside the courtroom, but can guarantee Mangione will receive a fair trial.

Authorities say Mangione gunned down Thompson as he was walking to an investor conference in midtown Manhattan on the morning of Dec 4.

Mangione was arrested in a Pennsylvania McDonald’s after a five-day search, carrying a gun that matched the one used in the shooting and a fake ID, police said. He also was carrying a notebook expressing hostility toward the health insurance industry and especially wealthy executives, according to federal prosecutors.

At a news conference last week, Manhattan District Attorney Alvin Bragg said the application of the terrorism law reflected the severity of a “frightening, well-planned, targeted murder that was intended to cause shock and attention and intimidation.”

“In its most basic terms, this was a killing that was intended to evoke terror,” he added.

Mangione is being held in a Brooklyn federal jail alongside several other high-profile defendants, including Sean “Diddy” Combs and Sam Bankman-Fried.

During his court appearance Monday, he smiled at times when talking with his attorneys and stretched his right hand after an officer removed his cuffs.

Workers at seven Amazon facilities went on strike Thursday, an effort by the Teamsters to pressure the e-commerce company for a labor agreement during a key shopping period.

The Teamsters say the workers, who authorized strikes in the past few days, are joining the picket line after Amazon ignored a Sunday deadline the union set for contract negotiations. Amazon says it doesn’t expect an impact on its operations during what the union calls the largest strike against the company in U.S. history.

The International Brotherhood of Teamsters say they represent nearly 10,000 workers at 10 Amazon facilities, a small portion of the 1.5 million people Amazon employs in its warehouses and corporate offices.

At one warehouse, located in New York City’s Staten Island borough, thousands of workers who voted for the Amazon Labor Union in 2022 and have since affiliated with the Teamsters. At the other facilities, employees - including many delivery drivers - have unionized with them by demonstrating majority support but without holding government-administered elections.

The strikes happening Thursday are taking place at one Amazon warehouse in San Francisco, California, and six delivery stations in southern California, New York City; Atlanta, Georgia, and Skokie, Illinois, according to the union’s announcement. Amazon workers at the other facilities are “prepared to join,” the union said.

“Amazon is pushing its workers closer to the picket line by failing to show them the respect they have earned,” Teamsters General President Sean M. O’Brien said in a statement.

The Seattle-based online retailer has been seeking to re-do the election that led to the union victory at the warehouse on Staten Island, which the Teamsters now represent. In the process, the company has filed a lawsuit challenging the constitutionality of the National Labor Relations Board.

TikTok on Monday asked the Supreme Court to step in on an emergency basis to block the federal law that would ban the popular platform in the United States unless its China-based parent company agreed to sell it.

Lawyers for the company and China-based ByteDance urged the justices to step in before the law’s Jan. 19 deadline. A similar plea was filed by content creators who rely on the platform for income and some of TikTok’s more than 170 million users in the U.S.

“A modest delay in enforcing the Act will create breathing room for this Court to conduct an orderly review and the new Administration to evaluate this matter — before this vital channel for Americans to communicate with their fellow citizens and the world is closed,” lawyers for the companies told the Supreme Court.

President-elect Donald Trump, who once supported a ban but then pledged during the campaign to “save TikTok,” said his administration would take a look at the situation.

“As you know, I have a warm spot in my heart for TikTok,” Trump said during a news conference at his Mar-a-Lago club in Florida. His campaign saw the platform as a way to reach younger, less politically engaged voters.

Trump was meeting with TikTok CEO Shou Zi Chew at Mar-a-Lago on Monday, according to two people familiar with the president-elect’s plans who were not authorized to speak publicly about them and spoke to The Associated Press on condition of anonymity.

The companies have said that a shutdown lasting just a month would cause TikTok to lose about a third of its daily users in the U.S. and significant advertising revenue.

The case could attract the court’s interest because it pits free speech rights against the government’s stated aims of protecting national security, while raising novel issues about social media platforms.

The request first goes to Chief Justice John Roberts, who oversees emergency appeals from courts in the nation’s capital. He almost certainly will seek input from all nine justices.

On Friday, a panel of federal judges on the U.S. Court of Appeals for the District of Columbia Circuit denied an emergency plea to block the law, a procedural ruling that allowed the case to move to the Supreme Court.

South Korea’s opposition leader offered Sunday to work with the government to ease the political tumult as officials sought to reassure allies and markets, a day after the opposition-controlled parliament voted to impeach conservative President Yoon Suk Yeol over a short-lived attempt to impose martial law.

Liberal Democratic Party leader Lee Jae-myung, whose party holds a majority in the National Assembly, urged the Constitutional Court to rule swiftly on Yoon’s impeachment and proposed a special council for policy cooperation between the government and parliament.

Yoon’s powers have been suspended until the court decides whether to remove him from office or reinstate him. If Yoon is dismissed, a national election to choose his successor must be held within 60 days.

Lee, who has led a fierce political offensive against Yoon’s embattled government, is seen as the frontrunner to replace him. He lost the 2022 presidential election to Yoon by a razor-thin margin.

He told a televised news conference that a swift court ruling would be the only way to “minimize national confusion and the suffering of people.”

The court will meet to discuss the case Monday, and has up to 180 days to rule. But observers say that a court ruling could come faster. In the case of parliamentary impeachments of past presidents — Roh Moo-hyun in 2004 and Park Geun-hye in 2016 — the court spent 63 days and 91 days respectively before determining to reinstate Roh and dismiss Park.

Lee also proposed a national council where the government and the National Assembly would work together to stabilize state affairs, and said his party won’t seek to impeach Prime Minister Han Duck-soo, a Yoon appointee who’s now serving as acting president.

The Supreme Court on Monday rejected an appeal from Wisconsin parents who wanted to challenge a school district’s guidance for supporting transgender students.

The justices, acting in a case from Eau Claire, left in place an appellate ruling dismissing the parents’ lawsuit.

Three justices, Samuel Alito, Brett Kavanaugh and Clarence Thomas, would have heard the case. That’s one short of what is needed for full review by the Supreme Court.

Parents with children in Eau Claire public schools argued in a lawsuit that the school district’s policy violates constitutional protections for parental rights and religious freedom.

Sixteen Republican-led states had urged the court to take up the parents’ case.

Lower courts had found that the parents lacked the legal right, or standing. Among other reasons, the courts said no parent presented evidence that the policy affected them or their children.

A unanimous three-judge panel of the 7th U.S. Circuit Court of Appeals included two judges Republican Donald Trump appointed during his first term.

But Alito described the case as presenting “a question of great and growing national importance,” whether public school districts violate parents’ rights when they encourage students to transition or assist in the process without parental consent or knowledge.

“Administrative Guidance for Gender Identity Support” encourages transgender students to reach out to staff members with concerns and instructs employees to be careful who they talk to about a student’s gender identity, since not all students are “out” to their families.
