<div class="css-s99gbd StoryBodyCompanionColumn" data-testid="companionColumn-0"><div class="css-53u6y8"><p class="css-at9mc1 evys1bk0">Elon Musk’s Department of Government Efficiency has repeatedly posted error-filled data that inflated its success at saving taxpayer money. But after a series of news reports called out those mistakes, the group changed its tactics.</p><p class="css-at9mc1 evys1bk0">It began making its new mistakes harder to find, leaving its already secretive activities even less transparent than before.</p><p class="css-at9mc1 evys1bk0">Mr. Musk’s group posted a new set of claims to its website on March 2, saying it had saved taxpayers $10 billion by terminating 3,489 federal grants.</p><p class="css-at9mc1 evys1bk0">Previously when it posted new claims, DOGE, Mr. Musk’s government-restructuring effort, had included identifying details about the cuts it took credit for. That allowed the public to fact-check its work by comparing its figures with federal spending databases and talking to the groups whose funding had been cut.</p></div><aside aria-label="companion column" class="css-ew4tgv"></aside></div><div data-testid="Dropzone-1"></div><div class="css-s99gbd StoryBodyCompanionColumn" data-testid="companionColumn-1"><div class="css-53u6y8"><p class="css-at9mc1 evys1bk0">This time, it did not include those details. A White House official said that was done for security purposes.</p><p class="css-at9mc1 evys1bk0">The result was that the group’s new claims appeared impossible to check.</p><p class="css-at9mc1 evys1bk0">The New York Times, at first, found a way around the group’s obfuscation. That is because Mr. Musk’s group had briefly embedded the federal identification numbers of these grants in the publicly available source code. The Times used those numbers to match DOGE’s claims with reality, and to discover that they contained the same kind of errors that it had made in the past.</p><div class="css-1336jj"><div class="css-121kum4"><div class="css-171quhb"></div><div class="css-asuuk5"><noscript><div class="css-7axq9l" data-testid="optimistic-truncator-noscript"><svg aria-hidden="true" class="css-1b5b8u1" height="24" viewbox="0 0 24 24" width="24"><path clip-rule="evenodd" d="M2.5 12a9.5 9.5 0 1 1 19 0 9.5 9.5 0 0 1-19 0Zm8.5 1.75v-7.5h2v7.5h-2Zm0 2v2h2v-2h-2Z" fill="currentColor" fill-rule="evenodd"></path></svg><div class="css-6yo1no" data-testid="optimistic-truncator-noscript-message"><p class="css-3kpklk">We are having trouble retrieving the article content.</p><p class="css-3kpklk">Please enable JavaScript in your browser settings.</p></div></div></noscript><div class="css-1dv1kvn" id="optimistic-truncator-a11y" tabindex="-1"><hr/><p>Thank you for your patience while we verify access.
