Arizona prosecutors pressing the case against Republicans who are accused of trying to overturn the 2020 election results in President Donald Trump’s favor were dealt a setback when a judge ordered the case be sent back to a grand jury.

Arizona’s fake elector case remains alive after Friday’s ruling by Maricopa County Superior Court Judge Sam Myers, but it’s being sent back to the grand jurors to determine whether there’s probable cause that the defendants committed the crimes.

The decision, first reported by the Washington Post, centered on the Electoral Count Act, a law that governs the certification of a presidential contest and was part of the defendants’ claims they were acting lawfully.

While the law was discussed when the case was presented to the grand jury and the panel asked a witness about the law’s requirements, prosecutors didn’t show the statute’s language to the grand jury, Myers wrote. The judge said a prosecutor has a duty to tell grand jurors all the applicable law and concluded the defendants were denied “a substantial procedural right as guaranteed by Arizona law.”

Richie Taylor, a spokesperson for Arizona Attorney General Kris Mayes, a Democrat whose office is pressing the case in court, said in a statement that prosecutors will appeal the decision. “We vehemently disagree with the court,” Taylor said.

Mel McDonald, a former county judge in metro Phoenix and former U.S. Attorney for Arizona, said courts send cases back to grand juries when prosecutors present misleading or incomplete evidence or didn’t properly instruct panel members on the law.

“They get granted at times. It’s not often,” said McDonald, who isn’t involved in the case.

In all, 18 Republicans were charged with forgery, fraud and conspiracy. The defendants consist of 11 Republicans who submitted a document falsely claiming Trump won Arizona, two former Trump aides and five lawyers connected to the former president, including Rudy Giuliani.

Two defendants have already resolved their cases, while the others have pleaded not guilty to the charges. Trump wasn’t charged in Arizona, but the indictment refers to him as an unindicted coconspirator.

Most of the defendants in the case also are trying to get a court to dismiss their charges under an Arizona law that bars using baseless legal actions in a bid to silence critics.

They argued Mayes tried to use the charges to silence them for their constitutionally protected speech about the 2020 election and actions taken in response to the race’s outcome. Prosecutors said the defendants didn’t have evidence to back up their retaliation claim and that they crossed the line from protected speech to fraud.

Eleven people who had been nominated to be Arizona’s Republican electors met in Phoenix on Dec. 14, 2020, to sign a certificate saying they were “duly elected and qualified” electors and claimed Trump had carried the state in the 2020 election.

President Joe Biden won Arizona by 10,457 votes. A one-minute video of the signing ceremony was posted on social media by the Arizona Republican Party at the time. The document later was sent to Congress and the National Archives, where it was ignored.

Prosecutors in Michigan, Nevada, Georgia and Wisconsin have also filed criminal charges related to the fake electors scheme.

A federal judge on Thursday barred the Trump administration from deporting any Venezuelans from South Texas under an 18th-century wartime law and said President Donald Trump’s invocation of it was “unlawful.”

U.S. District Court Judge Fernando Rodriguez Jr. is the first judge to rule that the Alien Enemies Act cannot be used against people who, the Republican administration claims, are gang members invading the United States. Rodriguez said he wouldn’t interfere with the government’s right to deport people in the country illegally through other means, but it could not rely on the 227-year-old law to do so.

“Neither the Court nor the parties question that the Executive Branch can direct the detention and removal of aliens who engage in criminal activity in the United States,” wrote Rodriguez, who was nominated by Trump in 2018. But, the judge said, “the President’s invocation of the AEA through the Proclamation exceeds the scope of the statute and is contrary to the plain, ordinary meaning of the statute’s terms.”

In March, Trump issued a proclamation claiming that the Venezuelan gang Tren de Aragua was invading the U.S. He said he had special powers to deport immigrants, identified by his administration as gang members, without the usual court proceedings.

“The Court concludes that the President’s invocation of the AEA through the Proclamation exceeds the scope of the statute and, as a result, is unlawful,” Rodriguez wrote.

In an interview on Fox News, Vice President JD Vance said the administration will be “aggressively appealing” the ruling and others that hem in the president’s deportation power.

“The judge doesn’t make that determination, whether the Alien Enemies Act can be deployed,” Vance said. “I think the president of the United States is the one who determines whether this country is being invaded.”

The chair of the Congressional Hispanic Caucus, Rep. Adriano Espaillat, D-N.Y., said in a statement the judge had made clear “what we all knew to be true: The Trump administration illegally used the Alien Enemies Act to deport people without due process.”

The Alien Enemies Act has only been used three times before in U.S. history, most recently during World War II, when it was cited to intern Japanese-Americans.

The proclamation triggered a flurry of litigation as the administration tried to ship migrants it claimed were gang members to a notorious prison in El Salvador.

Rodriguez’s ruling is significant because it is the first formal permanent injunction against the administration using the AEA and contends the president is misusing the law. “Congress never meant for this law to be used in this manner,” said Lee Gelernt, the ACLU lawyer who argued the case, in response to the ruling.

Rodriguez agreed, noting that the provision has only been used during the two World Wars and the War of 1812. Trump claimed Tren de Aragua was acting at the behest of the Venezuelan government, but Rodriguez found that the activities the administration accused it of did not amount to an invasion or “predatory incursion,” as the statute requires.

“The Proclamation makes no reference to and in no manner suggests that a threat exists of an organized, armed group of individuals entering the United States at the direction of Venezuela to conquer the country or assume control over a portion of the nation,” Rodriguez wrote. “Thus, the Proclamation’s language cannot be read as describing conduct that falls within the meaning of ‘invasion’ for purposes of the AEA.”

If the administration appeals, it would go first to the New Orleans-based 5th U.S. Circuit Court of Appeals. That is among the nation’s most conservative appeals courts and it also has ruled against what it saw as overreach on immigration matters by both the Obama and Biden administrations. In those cases, Democratic administrations had sought to make it easier for immigrants to remain in the U.S.

The administration, as it has in other cases challenging its expansive view of presidential power, could turn to appellate courts, including the U.S. Supreme Court, in the form of an emergency motion for a stay pending an appeal.

The Supreme Court already has weighed in once on the issue of deportations under the AEA. The justices held that migrants alleged to be gang members must be given “reasonable time” to contest their removal from the country. The court has not specified the length of time.

It’s possible that the losing side in the 5th Circuit would file an emergency appeal with the justices that also would ask them to short-circuit lower court action in favor of a definitive ruling from the nation’s highest court. Such a decision likely would be months away, at least.

The Texas case is just one piece of a tangle of litigation sparked by Trump’s proclamation.

Social media company Meta said Monday that it will start using publicly available content from European users to train its artificial intelligence models, resuming work put on hold last year after activists raised concerns about data privacy.

The company, which owns Facebook and Instagram, said that it would train its AI systems using public posts and comments shared by adult users in the 27-nation European Union.

“People’s interactions with Meta AI — like questions and queries — will also be used to train and improve our models,” the company said in a blog post.

Meta is making the move after launching its Meta AI assistant last month for European users, long after it rolled out to the United States and other major markets.

The company’s AI training efforts had been hampered by stringent European Union data privacy laws, which give people control over how their personal information is used. Vienna-based group NOYB, led by activist Max Schrems, had complained to various national privacy watchdogs about Meta’s AI training plans and urged them to stop the company before it started training its next generation of AI models.

Meta noted that a panel of EU privacy regulators in December “affirmed” that its original approach met legal obligations. The company said it won’t use private messages to train its AI model and repeated its point that it is merely following the example of rivals Google and OpenAI, “both of which have already used data from European users to train their AI models.”

Meta said it will start notifying users in the EU about the training, and will include a link to a form where they can object at any time.
