President Donald Trump says he is considering “taking away” the U.S. citizenship of a longtime rival, actress and comedian Rosie O’Donnell, despite a decades-old Supreme Court ruling that expressly prohibits such an action by the government.

“Because of the fact that Rosie O’Donnell is not in the best interests of our Great Country, I am giving serious consideration to taking away her Citizenship,” Trump wrote in a social media post on Saturday. He added that O’Donnell, who moved to Ireland in January, should stay in Ireland “if they want her.”

The two have criticized each other publicly for years, an often bitter back-and-forth that predates Trump’s involvement in politics. In recent days, O’Donnell on social media denounced Trump and recent moves by his administration, including the signing of a massive GOP-backed tax breaks and spending cuts plan.

It’s just the latest threat by Trump to revoke the citizenship of people with whom he has publicly disagreed, most recently his former adviser and one-time ally, Elon Musk.

But O’Donnell’s situation is notably different from Musk, who was born in South Africa. O’Donnell was born in the United States and has a constitutional right to U.S. citizenship. The U.S. State Department notes on its website that U.S. citizens by birth or naturalization may relinquish U.S. nationality by taking certain steps – but only if the act is performed voluntary and with the intention of relinquishing U.S. citizenship.

Amanda Frost, a law professor at the University of Virginia School of Law, noted the Supreme Court ruled in a 1967 case that the Fourteen Amendment of the Constitution prevents the government from taking away citizenship.

“The president has no authority to take away the citizenship of a native-born U.S. citizen,” Frost said in an email Saturday. “In short, we are nation founded on the principle that the people choose the government; the government cannot choose the people.”

O’Donnell moved to Ireland after Trump defeated Vice President Kamala Harris to win his second term. She has said she’s in the process of obtaining Irish citizenship based on family lineage.

Responding to Trump Saturday, O’Donnell wrote on social media that she had upset the president and “add me to the list of people who oppose him at every turn.”

State and local officials blasted the Trump administration’s widely anticipated list of “sanctuary” jurisdictions that are deemed uncooperative with federal immigration enforcement, with some of the most enthusiastic supporters of the White House wondering on Friday how they wound up on it.

The list, which was riddled with misspellings, included sparsely populated counties that have little interaction with immigration authorities, that overwhelmingly voted for President Donald Trump and that have actively supported his hard-line immigration policies.

In California, the city of Huntington Beach made the list of hundreds even though it filed a lawsuit challenging the state’s immigration sanctuary law and passed a resolution this year declaring the community a “non-sanctuary city.”

“At first when I heard it I was like, accidents happen,” said Huntington Beach Mayor Pat Burns. But after seeing so many other cities lumped in like his, he called it “negligent.” “You don’t have that many mistakes on such an important federal document ? somebody’s got to answer to that.”

Meanwhile, those with policies protecting immigrants also pushed back, saying they are doing right by their communities.

“This is simply the latest attempt by the Trump administration to strong-arm cities like Seattle into changing our local policies through bluster and threats to critical federal funding for public safety and homelessness,” Bruce Harrell, the city’s mayor, told The Associated Press in an email. “It’s not going to work ? the law is on our side ? and we will not hesitate to protect our people and stand up for our values.”

The list was published as the Trump administration ramps up efforts to follow through on the president’s campaign promises to remove millions of people who are in the country illegally. It came out as Immigration and Customs Enforcement announced major leadership changes, and after a White House official said the administration wanted to increase daily immigration arrests.

Misspelled communities on the list included Cincinnati, which was spelled Cincinnatti. Also, some counties were mislabeled as cities and vice versa.

The administration has said each listed jurisdiction will receive formal notification that the government has deemed them noncompliant and if they’re believed to be in violation of any federal criminal statutes.

In response to questions Friday about the list, the Department of Homeland security reiterated that it was compiled using a number of factors, including whether the localities identified themselves as sanctuary jurisdictions, how much they complied with federal officials enforcing immigration laws, if they had restrictions on sharing information with immigration enforcement or had any legal protections for people in the country illegally.

An appeals court ruled Friday that President Donald Trump can fire two board members of independent agencies handling labor issues from their respective posts in the federal government.

A divided three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit agreed to lift orders blocking the Trump administration from removing Merit Systems Protection Board member Cathy Harris and National Labor Relations Board member Gwynne Wilcox.

On March 4, U.S. District Judge Rudolph Contreras ruled that Trump illegally tried to fire Harris. Two days later, U.S. District Judge Beryl Howell ruled that Trump did not have the authority to remove Wilcox.

The Justice Department asked the appellate court to suspend those orders while they appeal the decisions.

President Joe Biden nominated Harris to the MSPB in 2021 and nominated Wilcox to a second five-year term as an NLRB member in 2023.

Circuit Judge Justin Walker, a Trump nominee, said the administration likely will succeed in showing that the statutory removal protections for NLRB and MSPB members are unconstitutional.

“The Government has also shown that it will suffer irreparable harm each day the President is deprived of the ability to control the executive branch,” Walker wrote.

Judge Karen LeCraft Henderson, who was nominated by Republican President George H.W. Bush, wrote an opinion concurring with Walker. Henderson said she agrees with Walker on many of the “general principles” about the contours of presidential power under the Constitution.

Judge Patricia Millett, who was nominated by Democratic President Barack Obama, wrote a dissenting opinion. She said her two colleagues on the case “rewrite controlling Supreme Court precedent and ignore binding rulings of this court, all in favor of putting this court in direct conflict with at least two other circuits.”

“The stay decision also marks the first time in history that a court of appeals, or the Supreme Court, has licensed the termination of members of multimember adjudicatory boards statutorily protected by the very type of removal restriction the Supreme Court has twice unanimously upheld,” Millett wrote.

Government lawyers argued that Trump had the authority to remove both board members. In Wilcox’s case, they said Howell’s “unprecedented order works a grave harm to the separation of powers and undermines the President’s ability to exercise his authority under the Constitution.” They also argued that MSPB members like Harris are removable “at will” by the president.

Wilcox’s attorneys said Trump couldn’t fire her without notice, a hearing or identifying any “neglect of duty or malfeasance in office” on her part. They argued that the administration’s “only path to victory” is to persuade the U.S. Supreme Court to “adopt a more expansive view of presidential power.”

Harris’ attorneys claimed the administration was asking the appeals court to ignore Supreme Court precedent.

“Make no mistake: The government’s radical theory would upend the law,” they wrote. “It would jeopardize not only this board, but also the Federal Reserve Board and other critical entities, like the Securities and Exchange Commission.”

The five-member NLRB lacked a quorum after Wilcox’s removal. The three-member MSPB enforces civil rights law in the workplace.
