Rosie O’Donnell, the liberal actress and comic, apologized on social media Sunday after falsely claiming the Minneapolis Catholic church school shooter was a MAGA supporter, a Republican and a white supremacist.

Last Thursday, O’Donnell posted a video after learning about the attack that left two children dead and 18 others injured, 15 of them kids.

The comedian said the violence reminded her of the Columbine massacre in 1999, when she struggled to comprehend that American students were shooting each other in schools.

Regarding the Minneapolis shooting, O’Donnell pointed out it took place inside a Catholic school and added: "What do you know? It was a white guy, Republican, MAGA person. What do you know? White supremacists."

By Sunday, O’Donnell walked back her comments, admitting she was wrong about the shooter’s identity.

"I knew a lot of you were very upset about the video I made before I went away for a few days," she said in a new video, adding that she did not have time to read through the comments until Sunday. "You are right. I did not do my due diligence before I made that emotional statement, and I said things about the shooter that were incorrect.

"I assumed, like most shooters, they followed a standard MO and had standard, you know, feelings of… you know, NRA-loving kind of gun people," O’Donnell continued. "Anyway, the truth is I messed up, and when you mess up, you fess up. I’m sorry. This is my apology video and I hope it’s enough."

Her apology drew sharp criticism online. One user called it "the most unapologetic apology ever." Another wrote, "She’s not sorry, she still means exactly what she said." A third said she was "trying to save face, because she opened her mouth and was so wrong."

In the comments, O’Donnell replied to one critic, writing, "I was wrong - and I apologize - what more do [you] want?"

Others said the misstep reflected a bigger problem. "It’s good that you apologized, but this is what is keeping this country so divided," one person wrote. "So much mistruths being spread by both sides. People need to fact check every single political thing that they see because the majority of it is a lie."

O’Donnell’s remarks came less than a week after the gunman opened fire during a Mass at Annunciation Catholic Church in Minneapolis, where students from the attached school were gathered.

The gunfire shattered stained-glass and pew-side windows as students and parishioners ducked for cover.

FBI Director Kash Patel said Thursday the "barbaric" attack appeared to be an act of domestic terrorism "motivated by a hate-filled ideology."

Patel said the shooter’s manifesto and writings on firearms expressed anti-Catholic and anti-religious themes, along with violent antisemitic messages. Among them were phrases such as "Israel must fall" and "Free Palestine," alongside Holocaust-related slurs.

A Biden-appointed federal judge abruptly blocked the Trump administration from flying out hundreds of illegal alien children over Labor Day weekend after immigrant advocacy groups rushed to court, claiming Trump was carrying out a mass deportation in the dead of night.

The emergency order by U.S. District Judge Sparkle Sooknanan froze a pilot program the administration said would reunite nearly 700 kids with parents or guardians in Guatemala.

By the time the judge intervened, charter buses had already rolled up to planes in Harlingen and El Paso and, in some cases, children were seated on board awaiting departure.

Justice Department lawyer Drew Ensign told the court, "These are not removals under the statute. These are repatriations. All of these children have parents or guardians in Guatemala who have requested their return."

Advocacy groups rejected that explanation, with the National Immigration Law Center's (NILC) Efrén Olivares firing back that "it is a dark and dangerous moment when our government chooses to target orphaned 10-year-olds."

The lawsuit, LGML v. Noem, was filed just after 1 a.m. Sunday, accusing the Trump administration of skirting a 2008 law that immigrant-rights groups often cite to shield minors from removal. 

Named as defendants were Attorney General Pam Bondi, Department of Homeland Security Secretary Kristi Noem, Health and Human Services Secretary Robert F. Kennedy Jr. and Secretary of State Marco Rubio.

FEDERAL JUDGE HALTS TRUMP ADMINISTRATION DEPORTATION OF EIGHT MIGRANTS TO SOUTH SUDAN

The lead plaintiff was a 10-year-old girl identified only by her initials whose mother had died in Guatemala. Judge Sooknanan scolded the Trump administration over the timing, saying during the emergency hearing: "I have the government attempting to remove minor children from the country in the wee hours of the morning on a holiday weekend, which is surprising, but here we are."

The Trump administration insists the flights were lawful reunifications negotiated with Guatemala’s government, while advocacy groups argue the kids are being rushed out without hearings or the chance to pursue asylum. 

Guatemala’s foreign minister confirmed the country is ready to take the children, with President Bernardo Arévalo calling it a "moral and legal obligation."

Unaccompanied children who arrive illegally in the United States are often handed over to the HHS' Office of Refugee Resettlement (ORR) while their immigration cases are prepared. Those from Guatemala often request asylum to stay in America.

For now, hundreds of Guatemalan minors remain in the U.S. while the legal battle plays out. According to reporting from The Associated Press, family members of many of the migrants had gathered at airports across the Central American nation in anticipation of their arrival.
