Elon Musk made a clear promise after Donald Trump decided to put him in charge of making the government more efficient.

“It’s not going to be some sort of backroom secret thing,” Musk said last year. “It will be as transparent as possible,” maybe even streamed live online. It hasn’t worked out that way so far.

In the three weeks since the Republican president has been back in the White House, Musk has rapidly burrowed deep into federal agencies while avoiding public scrutiny of his work. He has not answered questions from journalists or attended any hearings with lawmakers. Staff members for his so-called Department of Government Efficiency, or DOGE, have sidelined career officials around Washington.

It is a profound challenge not only to business-as-usual within the federal government, which Trump campaigned on disrupting, but to concepts of consensus and transparency that are foundational in a democratic system. Musk describes himself as “White House tech support,” and he has embedded himself in an unorthodox administration where there are no discernible limits on his influence.

Donald K. Sherman, executive director of Citizens for Responsibility and Ethics in Washington, said Trump has allowed Musk to “exert unprecedented power and authority over government systems” with “maximal secrecy and little-to-no accountability.”

The White House insisted that DOGE is “extremely transparent” and shared examples of its work so far, such as canceling contracts and ending leases for underused buildings. House Republicans said the Trump administration also discovered that Social Security benefits were being paid to a dozen people listed as 150 years old.

“We’re going to find billions, hundreds of billions of dollars of fraud and abuse and, you know, the people elected me on that,” Trump said in a Fox News interview to be aired along with the Super Bowl on Sunday. He described Musk as “terrific” and said he would soon focus on the Department of Defense, the country’s largest government agency.

That is true, at least judging by Musk’s social media, where no thought appears to be suppressed. His X account is a flood of internet memes, attacks on critics and professions of loyalty to the president. He has made clear the grand scope of his ambitions, talking in existential terms about the need to reverse the federal deficit, cut government spending and roll back progressive programs.

“This administration has one chance for major reform that may never come again,” he posted on Saturday. “It’s now or never.”

Musk is used to doing things his own way. The world’s richest person, he became wealthy with the online payment service PayPal, then took over the electric car manufacturer Tesla and founded the rocket company SpaceX. More recently, he bought Twitter and rebranded it as X, cutting jobs and remaking its culture.

The Arizona Supreme Court unanimously ruled Friday that nearly 98,000 people whose citizenship documents hadn’t been confirmed can vote in state and local races, a significant decision that could influence ballot measures and tight legislative races.

The court’s decision comes after officials uncovered a database error that for two decades mistakenly designated the voters as having access to the full ballot. The voters already were entitled to cast ballots in federal races, including for president and Congress, regardless of how the court ruled.

Secretary of State Adrian Fontes, a Democrat, and Stephen Richer, the Republican Maricopa County recorder, had disagreed on what status the voters should hold. Richer asked the high court to weigh in, saying Fontes ignored state law by advising county officials to let affected voters cast full ballots.

Fontes said not allowing the voters who believed they had satisfied voting requirements access to the full ballot would raise equal protection and due process concerns.

The high court, which leans Republican, agreed with Fontes. It said county officials lack the authority to change the voters’ statuses because those voters registered long ago and had attested under the penalty of law that they are citizens. The justices also said the voters were not at fault for the database error and also mentioned the little time that’s left before the Nov. 5 general election.

“We are unwilling on these facts to disenfranchise voters en masse from participating in state contests,” Chief Justice Ann Scott Timmer wrote in the ruling.

Of the nearly 98,000 affected voters, most of them reside in Maricopa County, which is home to Phoenix, and are longtime state residents who range in age from 45 to 60. About 37% of them are registered Republicans, about 27% are registered Democrats and the rest are independents or affiliated with minor parties.

Arizona is unique among states in that it requires voters to prove their citizenship to participate in local and state races. Voters can demonstrate citizenship by providing a driver’s license or tribal ID number, or they can attach a copy of a birth certificate, passport or naturalization documents.

Arizona considers drivers’ licenses issued after October 1996 to be valid proof of citizenship. However, a system coding error marked nearly 98,000 voters who obtained licenses before 1996 — roughly 2.5% of all registered voters — as full-ballot voters, state officials said.

New York’s highest court heard arguments Tuesday in a Republican challenge of a law that allows any registered voter to cast a mail-in ballot during the early voting period.

The case, which is led by Rep. Elise Stefanik and includes other lawmakers and the Republican National Committee, is part of a widespread GOP effort to tighten voting rules after the 2020 election.

Democrats approved the mail voting expansion law last year. The Republican challenge argues that it violates voting provisions in the state Constitution.

The hourlong arguments before the New York Court of Appeals in Albany hinged on technical readings of the Constitution, specifically whether certain passages would allow for the state Legislature to expand mail voting access.

At certain points in the hearing, judges quizzed attorneys on whether a constitutional provision that says eligible voters are entitled to vote “at every election” would mean a physical polling place or simply the election in general.

Michael Y. Hawrylchak, an attorney representing the Republicans, said that provision “presupposes a physical place” for in-person voting. Deputy Solicitor General Jeffrey W. Lang, who is representing the state, said the phrase “just refers to a process of selecting an office holder” and not any physical polling place.

Democrats first tried to expand mail voting through a constitutional amendment in 2021, but voters rejected the proposal after a campaign from conservatives who said it would lead to voter fraud.

Lower courts have dismissed the Republican lawsuit in decisions that said the Legislature has the constitutional authority to make rules on voting and the Constitution doesn’t require voting specifically to occur in person on election day.

It is unclear when the Court of Appeals will rule.
