A man who sprayed vinegar at Democratic U.S. Rep. Ilhan Omar at a town hall meeting in Minneapolis pleaded guilty to assault Thursday in federal court after reaching a deal with prosecutors.

Anthony Kazmierczak, 55, is awaiting sentencing.

Kazmierczak, dressed in bright orange jail clothing, gave only a fragmentary explanation Thursday of the Jan. 27 assault, which came as the city was already on edge after the fatal shootings of two people by federal agents during a White House crackdown that brought thousands of immigration officers to Minnesota.

After being asked what he remembered of the assault, he told U.S. District Judge Joan N. Ericksen: "It's fuzzy."

Kazmierczak, who was in the audience during Omar's January town hall, leaped up when the representative called for the ouster of then-Homeland Security Secretary Kristi Noem. He sprayed liquid from a syringe as court documents say he shouted that Noem would not resign and that Omar was "splitting Minnesota apart."

Security officers tackled Kazmierczak, who told them the liquid was vinegar.

"I didn't want anybody to think she was in danger," he said Thursday.

Omar, who was not injured, continued with the town hall after the arrest.

Authorities later determined he'd sprayed her with a mixture of water and apple cider vinegar. He was charged with assaulting a U.S. officer.

Court documents say Kazmierczak, a critic of Omar who has made online posts supportive of President Donald Trump, told a close associate several years ago that "somebody should kill" her.

Omar, a refugee from Somalia, has long been a target of Trump's anti-immigrant rhetoric. After she was elected seven years ago, Trump said she should "go back" to her home country. He has described her as "garbage" and said she should be investigated.

Trump has also accused Omar of staging the attack, telling ABC News, "She probably had herself sprayed, knowing her."

On Thursday, Kazmierczak told Erickson that he was being treated for Parkinson's disease, and that he'd been diagnosed with ADHD or attention-deficit/hyperactivity disorder, and a form of post-traumatic stress.

After his arrest, his then-attorney said that he did not have access to the medications he needed for Parkinson's and other serious conditions.

Minnesota court records show that Kazmierczak, who was convicted of felony auto theft in 1989, has been arrested multiple times for driving under the influence and has had numerous traffic citations. There are also indications he has had significant financial problems, including two bankruptcy filings.

In social media posts, Kazmierczak had criticized former President Joe Biden and referred to Democrats as "angry and liars." Trump wants the U.S. to be "stronger and more prosperous," he wrote.

Threats against members of Congress have increased in recent years, peaking in 2021 following the Jan. 6 attack on the U.S. Capitol by a mob of Trump supporters before dipping slightly, only to climb again, according to the most recent figures from the U.S. Capitol Police.

When a federal judge shot down a Trump administration policy of holding immigrants without bond last December, it seemed like a serious blow to the president's mass deportation effort.

Instead, a top Justice Department official insisted the ruling wasn't binding, and the administration continued denying detainees around the country a chance for release.

By February, the district court judge, Sunshine Sykes, was fed up. Sykes, a nominee of President Joe Biden, accused Trump officials in a ruling that month of seeking "to erode any semblance of separation of powers," adding that they could "only do so in a world where the Constitution does not exist."

Hardly isolated, the case illustrates a broader pattern of defiance of lower court decisions in President Donald Trump's second term.

The failure of Trump officials to follow court orders has been highlighted most notably in individual immigration cases. But a review of hundreds of pages of court records by The Associated Press also shows an extraordinary record of violations in lawsuits over policy changes and other moves.

In the second Trump administration's first 15 months in office, district court judges ruled it was violating an order in at least 31 lawsuits over a wide range of issues, including mass layoffs, deportations, spending cuts and immigration practices, the AP's review of court records found. That's about one out of every eight lawsuits in which courts have at least temporarily blocked the administration's actions.

The Republican administration's power struggle with federal courts — which is testing basic tenets of U.S. democracy — reflects an expansive view of executive authority that has also challenged the independence of federal agencies, a president's ethical obligations, and the U.S.'s role in the international order.

The violations in the 31 lawsuits are in addition to more than 250 instances of noncompliance judges have recently highlighted in individual immigration petitions — from failing to return property to keeping immigrants locked up past court-ordered release dates.

Legal scholars and former federal judges said they could recall at most a few violations of court rulings over the full four-year terms of other recent presidential administrations, including Trump's first time in office. They also noted previous administrations were generally apologetic when confronted by judges; the Trump administration's Justice Department has been outright combative in some cases.

"What the court system is experiencing in the last year and a half is just qualitatively completely different from anything that's preceded it," said Ryan Goodman, a law professor at New York University who studies federal courts and is tracking litigation against the Trump administration.

Though Trump officials eventually backed down in about a third of the 31 lawsuits, legal experts say their treatment of court orders poses serious dangers.

"The federal government should be the institution most devoted to the rule of law in this country," said David Super, a constitutional law scholar at Georgetown University. "When it ceases to feel itself bound, respect for the rule of law is likely to break down across the country."

The White House's aggressive policy moves have prompted a barrage of lawsuits — more than 700 and counting.

In October, U.S. District Judge William Smith took little time to conclude Homeland Security officials were flouting one of his orders. Smith, a nominee of George W. Bush, had blocked them from making billions of dollars in disaster relief funding to states contingent on cooperation with the president's immigration priorities.

Spirit Airlines, an impish upstart that shook the industry with its irreverent ads and deep discount fares, announced Saturday that it has gone out of business after 34 years.

The ultralow cost airline that once operated hundreds of daily flights on its bright yellow planes and employed about 17,000 people said it had "started an orderly wind-down of our operations, effective immediately."

The airline said on its website that all flights have been canceled and customer service is no longer available.

"We are proud of the impact of our ultra-low-cost model on the industry over the last 34 years and had hoped to serve our guests for many years to come," the announcement said.

U.S. Transportation Secretary Sean Duffy said Saturday that Spirit had a reserve fund set up for customers who bought directly from the airline to get refunds. People who bought from third-party vendors like travel agents would have to seek refunds from them. He had a stark message for people flying with Spirit.

"If you have a flight scheduled with Spirit Airlines, don't show up at the airport. There will be no one here to assist you," Duffy said.

He said United, Delta, JetBlue and Southwest were offering $200 one-way flights for people who could confirm that they had Spirit confirmation numbers and proof of purchase for a limited time. Duffy also said other airlines would help with Spirit employees who might be stranded as well as offering them a preferential application process as they look for work.

Spirit said in a statement it was working to get more than 1,300 crew to their home bases and that the final Spirit flight landed at Dallas Forth Worth International Airport from Detroit Metropolitan Airport.

The company advised customers that they could expect refunds but there would be no help in booking travel on other airlines.

Five Spirit flights were still showing as "on time" on Saturday morning on the departure board in Atlanta, one of the airline's smaller stations.

A trickle of passengers who hadn't heard the news were still showing up, including Joshua Sigler, who had bought a ticket Friday for a flight Saturday to Miami.

"I'm just going to go back home," said Sigler, who didn't try to take advantage of deals some other airlines were offering to displaced Spirit passengers.

He said he had gotten no communication from Spirit, which he had flown multiple times in the past. "They get you there," he said of past flights. "It was cheap."

Former Spirit flight attendant Freddy Peterson was on a Spirit flight from Detroit that arrived in Newark around 11 p.m. Friday. He said that despite rumors flying on social media Friday, things seemed kind of normal, with more than 200 passengers on the plane.

"All our aircraft were packed," he said.

Peterson, 60, said he set his alarm clock for 3 a.m. Saturday to check the company website at the hour of the rumored shutdown.

"I said, OK, well, since all this going on, they said Spirit is supposed to close at 3, I'm going to bed. I set my alarm clock for 3 o'clock, went onto the website and it said, 'Spirit flights have been canceled,'" Peterson said.

He said Delta Air Lines brought him and another flight attendant back to Atlanta on Saturday morning, with Peterson leaving from there to drive to his home in Shellman in southwest Georgia.

"I'll probably do my boo-hoo crying and all that other stuff once I get in the car."

Peterson said he had been a flight attendant with Spirit for 10 years and the company has "done wonders for me." He said the airline's reputation for bargain basement chaos was largely undeserved, but he did fault management for not communicating with the employees in the closing days, saying a promised employee town hall was canceled.

The Trump administration had considered a government bailout for the cash-strapped business to keep it from going under, but a deal was not reached. Of the potential bailout, Duffy said Saturday "we often times don't have half a billion dollars laying around."

President Donald Trump had floated the idea of a bailout last week after the airline found itself in bankruptcy proceedings for the second time in less than two years with jet fuel prices soaring because of the Iran war.

As late as Friday afternoon, Trump had said that "we're looking at it" and had given the budget carrier a "final proposal" for a taxpayer-funded takeover.

Spirit has struggled financially since the COVID-19 pandemic, weighed down by rising operating costs and growing debt. By the time it filed for Chapter 11 protection in November 2024, Spirit had lost more than $2.5 billion since the start of 2020.

The budget carrier sought bankruptcy protection again in August 2025, when it reported having $8.1 billion in debts and $8.6 billion in assets, according to court filings.

The White House had blamed President Joe Biden administration for Spirit's tenuous financial situation. Biden, a Democrat, opposed a proposed merger between Spirit and JetBlue in 2023. On Saturday, Trump administration officials took to social media to amplify voices of conservative critics who faulted Biden for Spirit's demise.

On Saturday, Duffy concentrated blame on Biden as well as his predecessar Pete Buttigieg.

"Many at the time said that this was a disaster. This merger should have been allowed," he said.

Supporters of a rescue including labor unions representing Spirit's pilots, flight attendants and ramp workers said a collapse would put thousands of Americans out of work and hurt consumers by reducing airline competition and increasing airfares. About 17,000 jobs could be impacted, according to Spirit lawyer Marshall Huebner.

Budget-conscious and leisure travelers would likely feel Spirit's absence the most, especially in places where the airline has a big footprint such as Las Vegas and the Florida cities of Fort Lauderdale and Orlando.

The carrier flew about 1.7 million domestic passengers in February, roughly half a million fewer than during the same month a year earlier, according to aviation analytics firm Cirium. Spirit also has sharply reduced its capacity, with about half as many seats available this month than in May 2024.

An appeals court on Friday blocked President Donald Trump's executive order suspending asylum access at the southern border of the U.S., a key pillar of the Republican president's plan to crack down on migration.

A three-judge panel from the U.S. Court of Appeals for the District of Columbia Circuit found that immigration laws give people the right to apply for asylum at the border, and the president can't circumvent that.

The court opinion stems from action taken by Trump on Inauguration Day 2025, when he declared that the situation at the southern border constituted an invasion of America and that he was "suspending the physical entry" of migrants and their ability to seek asylum until he decides it is over.

The panel concluded that the Immigration and Nationality Act doesn't authorize the president to remove the plaintiffs under "procedures of his own making," allow him to suspend plaintiffs' right to apply for asylum or curtail procedures for adjudicating their anti-torture claims.

"The power by proclamation to temporarily suspend the entry of specified foreign individuals into the United States does not contain implicit authority to override the INA's mandatory process to summarily remove foreign individuals," wrote Judge J. Michelle Childs, who was nominated to the bench by Democratic President Joe Biden.

"We conclude that the INA's text, structure, and history make clear that in supplying power to suspend entry by Presidential proclamation, Congress did not intend to grant the Executive the expansive removal authority it asserts," the opinion said.

The administration can ask the full appeals court to reconsider the ruling or go to the Supreme Court.

The order doesn't formally take effect until after the court considers any request to reconsider.

White House press secretary Karoline Leavitt, speaking on Fox News, said she had not seen the ruling but called it "unsurprising," blaming politically-motivated judges.

"They are not acting as true litigators of the law. They are looking at these cases from a political lens," she said.

Leavitt said Trump was taking actions that are "completely within his powers as commander in chief."

White House spokeswoman Abigail Jackson said the Department of Justice would seek further review of the decision. "We are sure we will be vindicated," she wrote in an emailed statement.

The Department of Homeland Security said it strongly disagreed with the ruling.

"President Trump's top priority remains the screening and vetting of all aliens seeking to come, live, or work in the United States," DHS said in a statement.

Aaron Reichlin-Melnick, senior fellow at the American Immigration Council, said that previous legal action had already paused the asylum ban, and the ruling won't change much on the ground.

The ruling, however, represents another legal defeat for a centerpiece policy of the president.

"This confirms that President Trump cannot on his own bar people from seeking asylum, that it is Congress that has mandated that asylum seekers have a right to apply for asylum and the President cannot simply invoke his authority to sustain," said Reichlin-Melnick.

Advocates say the right to request asylum is enshrined in the country's immigration law and say denying migrants that right puts people fleeing war or persecution in grave danger.

Lee Gelernt, attorney with the American Civil Liberties Union, who argued the case, said in a statement that the appellate ruling is "essential for those fleeing danger who have been denied even a hearing to present asylum claims under the Trump administration's unlawful and inhumane executive order."

Las Americas Immigrant Advocacy Center, one of the plaintiffs in the lawsuit, welcomed the court decision as a victory for their clients.
