Feds arrest embattled Sonoma developer suspected of ‘Ponzi scheme' that cost investors millions
Federal authorities Thursday accused embattled Sonoma real estate developer Kenneth Mattson of engaging in 'a classic Ponzi scheme' that stole tens of millions of dollars from hundreds of retirees and others who had entrusted him with their life savings.
In a 22-page indictment, federal prosecutors charged Mattson with seven counts of wire fraud, one count of money laundering, and one count of obstruction of justice for destroying records in a federal investigation.
The arrest comes one year after Mattson's longtime business partner, Timothy LeFever, accused him of bilking their company and clients in a scheme that apparently went undetected for years. Mattson denied those claims.
Using money they solicited from hundreds of investors, Mattson and LeFever amassed a large real estate portfolio in and around the city of Sonoma, and snapped up well-known and historic properties and businesses. Federal prosecutors said that Mattson presented the investments as 'legitimate and safe interests of limited partnerships that owned real estate,' but instead created fake documents and took the money.
According to federal prosecutors, Mattson took at least $28 million from investors for 'off-books' investments in two of his investment companies
'Instead of delivering the investment returns he promised, Mr. Mattson is charged with cheating these investors out of their hard-earned money and, in many cases, out of their life savings,' said Acting U.S. Attorney Patrick D. Robbins in a statement.
'Mr. Mattson will now be held to account on charges of perpetrating a scheme that he kept afloat only by using new investors' money to pay obligations to earlier investors.'
The crimes carry maximum sentences of 20 years in prison for each wire fraud and obstruction charge and 10 years for the charge of money laundering.
Mattson was scheduled to appear in federal court Friday. This is a developing story, check sfchronicle.com for updates.

Supreme Court rules DOGE can access Social Security information
The U.S. Supreme Court on Friday ruled the Department of Government Efficiency could access Social Security systems with sensitive information. The ruling blocked a lower Maryland court order that kept Doge from seeking certain Social Security information due to federal privacy laws. The data from the U.S. Social Security Administration includes Social Security numbers, medical information, citizenship records, school records, and tax returns for millions of Americans. Exclusive: Legal Institute Celebrates Scotus Decision, Declares 'Religious Liberty Is Alive And Well' "We conclude that, under the present circumstances, SSA may proceed to afford members of the SSA DOGE Team access to the agency records in question in order for those members to do their work," the court said in an unsigned order. The six conservative justices voted for the ruling and the three liberal justices, Ketanji Brown Jackson, Elena Kagan and Sonia Sotomayor dissented. Read On The Fox News App Doge Will Go On: Hill Pork Hawk Says Rooting Out Government Waste Will Continue After Elon Jackson said the ruling created "grave privacy risks" for millions of Americans by giving "unfettered data access to DOGE regardless — despite its failure to show any need or any interest in complying with existing privacy safeguards, and all before we know for sure whether federal law countenances such access." The ruling came soon after DOGE's former head, Elon Musk, left the government and a day after he and President Donald Trump traded personal attacks that were sparked by a disagreement over the president's "Big, Beautiful" bill. DOGE's path forward after Musk's exit isn't clear, but Trump and Musk have both previously said the newly-created agency's work would continue. The Trump administration has said DOGE needs access to Social Security information to continue its core task of rooting out government waste. Musk has previously called Social Security a "Ponzi scheme," and insisted on eliminating waste in the program. Maryland U.S. District Judge Ellen Hollander previously ruled that DOGE's efforts with Social Security were a "fishing expedition" based on "little more than suspicion" of fraud. She did allow some access, however, to anonymous data for DOGE workers who had gone through background checks. An appeals court didn't immediately lift the block, with dissenting conservative judges saying there's no evidence that DOGE has done any "targeted snooping" or exposed personal information.

DOGE team can access Social Security systems, US Supreme Court rules
The Supreme Court cleared the way Friday for the Department of Government Efficiency to access Social Security systems containing personal data on millions of Americans. The court majority sided with the Trump administration in its first Supreme Court appeal involving DOGE, the team once led by billionaire Elon Musk. The three liberal justices dissented. The high court halted an order from a judge in Maryland restricting the team's access to the Social Security Administration under federal privacy laws. The agency holds sensitive data on nearly everyone in the country, including school records, salary details and medical information. The Trump administration says DOGE needs access to carry out its mission of targeting waste and fraud in the federal government. Musk had been focused on Social Security as an alleged hotbed of fraud. The billionaire entrepreneur, who has stepped back from his work with DOGE, has described it as a ' Ponzi scheme ' and insisted that reducing waste in the program is an important way to cut government spending. U.S. District Judge Ellen Hollander in Maryland found that DOGE's efforts at Social Security amounted to a 'fishing expedition' based on 'little more than suspicion' of fraud, and allowing unfettered access puts Americans' private information at risk. Her ruling did allow access to anonymous data for staffers who have undergone training and background checks, or wider access for those who have detailed a specific need. The Trump administration has said DOGE can't work effectively with those restrictions. Solicitor General John Sauer also argued that the ruling is an example of federal judges overstepping their authority and trying to micromanage executive branch agencies. The plaintiffs say it's a narrow order that's urgently needed to protect personal information. An appeals court previously refused to immediately to lift the block on DOGE access, though it split along ideological lines. Conservative judges in the minority said there's no evidence that the team has done any 'targeted snooping' or exposed personal information. The lawsuit was originally filed by a group of labor unions and retirees represented by the group Democracy Forward. It's one of more than two dozen lawsuits filed over DOGE's work, which has included deep cuts at federal agencies and large-scale layoffs. The nation's court system has been ground zero for pushback to President Donald Trump's sweeping conservative agenda, with about 200 lawsuits filed challenging policies on everything from immigration to education to mass layoffs of federal workers.

Supreme Court allows DOGE team to access Social Security systems with data on millions of Americans
WASHINGTON (AP) — The Supreme Court handed the Trump administration two victories Friday in cases involving the Department of Government Efficiency, including giving it access to Social Security systems containing personal data on millions of Americans. The justices also separately reined in orders seeking transparency at DOGE, the team once led by billionaire Elon Musk. The court's conservative majority sided with the Trump administration in the first Supreme Court appeals involving DOGE. The three liberal justices dissented in both cases. The DOGE victories come amid a messy breakup between the president and the world's richest man that started shortly after Musk's departure from the White House and has included threats to cut government contracts and a call for the president to be impeached. The future of DOGE's work isn't clear without Musk at the helm, but both men have previously said that it will continue its efforts. In one case, the high court halted an order from a judge in Maryland that has restricted the team's access to the Social Security Administration under federal privacy laws. 'We conclude that, under the present circumstances, SSA may proceed to afford members of the SSA DOGE Team access to the agency records in question in order for those members to do their work,' the court said in an unsigned order. Conservative lower-court judges have said there's no evidence at this point of DOGE mishandling personal information. The agency holds sensitive data on nearly everyone in the country, including school records, salary details and medical information. Justice Ketanji Brown Jackson said the court's action creates 'grave privacy risks' for millions of Americans by giving 'unfettered data access to DOGE regardless — despite its failure to show any need or any interest in complying with existing privacy safeguards, and all before we know for sure whether federal law countenances such access.' Justice Sonia Sotomayor joined Jackson's opinion and Justice Elena Kagan said she also would have ruled against the administration. The Trump administration says DOGE needs the access to carry out its mission of targeting waste in the federal government. Musk had been focused on Social Security as an alleged hotbed of fraud. The entrepreneur has described it as a ' Ponzi scheme ' and insisted that reducing waste in the program is an important way to cut government spending. But U.S. District Judge Ellen Hollander in Maryland found that DOGE's efforts at Social Security amounted to a 'fishing expedition' based on 'little more than suspicion' of fraud, and allowing unfettered access puts Americans' private information at risk. Her ruling did allow access to anonymous data for staffers who have undergone training and background checks, or wider access for those who have detailed a specific need. The Trump administration has said DOGE can't work effectively with those restrictions. Solicitor General D. John Sauer also argued that the ruling is an example of federal judges overstepping their authority and trying to micromanage executive branch agencies.

The nation's court system has been ground zero for pushback to President Donald Trump's sweeping conservative agenda, with about 200 lawsuits filed challenging policies on everything from immigration to education to mass layoffs of federal workers. In the other DOGE order handed down Friday, the justices extended a pause on orders that would require the team to publicly disclose information about its operations, as part of a lawsuit filed by a government watchdog group. Citizens for Responsibility and Ethics in Washington argues that DOGE, which has been central to Trump's push to remake the government, is a federal agency and must be subject to the Freedom of Information Act. But the Trump administration says DOGE is just a presidential advisory body aimed at government cost-cutting, which would make it exempt from requests for documents under FOIA. The justices did not decide that issue Friday, but the conservative majority held that U.S. District Judge Christopher Cooper ruled too broadly in ordering documents be turned over to CREW.
