The summer swelter lingered in the swamp around President Donald Trump’s Washington in late July. Democrats in Congress continued to mull whether or not they would move to impeach him; Republicans, habitually, turned a blind eye to his hateful rhetoric and compulsive Twitter attacks. In New York the stock market teetered as traders awaited the administration’s next move on tariffs; prosecutors in the Southern District of New York appeared, without great logic or transparency, to close its campaign-finance investigation into Trump’s hush money payments without indicting anyone else involved apart from his longtime attorney Michael Cohen, who, by July, was more than two months into a three-year sentence at a federal facility in the Catskills.

While Cohen reads through the prison library and works out with “The Situation” in the Otisville Correctional Facility’s gym, his former neighbor on Park Avenue Stephanie Winston Wolkoff was having a different sort of summer. Last month, Wolkoff received a subpoena from the Washington, D.C., attorney general’s office, requesting documents related to President Trump’s inauguration, which Wolkoff had a heavy hand in planning. The $107 million event has been under investigation for months, including by federal prosecutors in New York and New Jersey, for profligate spending and questions about foreign donations. The latest subpoena appears to be probing potential self-dealing by the Trump Organization and members of the president’s family, according to two people familiar with the investigation.

Wolkoff complied with the request, according to these sources, by the July 26 deadline, which asked her to turn over records involving the inaugural event, the president’s family and associates, and expenditures by the inaugural committee that could shine a light on whether the nonprofit group provided private benefits to the Trump Organization. The attorney general appears to be particularly interested in payments being made through the inaugural committee to Trump-owned businesses, and whether there was a fair bidding process for contractors.

In response to a request for comment, Wolkoff said she signed a nondisclosure agreement and could not comment on any investigation, subpoena, or her cooperation. “If the [Presidential Inaugural Committee] wants to release me from this obligation, I would be able to speak freely without the fear of legal or financial repercussions,” she said in a statement. “Otherwise, I am regrettably unable to provide substantial comment.” Her lawyer did not respond to a request for comment. The White House declined to comment. A spokesperson for the attorney general’s office did not immediately respond.

The gulf between what Wolkoff knows and what she is publicly able to say can be measured in tens of thousands of documents, email exchanges, meeting minutes, and phone calls. She has, after all, known first lady Melania Trump for years, making her one of a small circle of confidants. As I reported earlier this year, the two were close enough that she would spend the night in the residence at the White House with the first lady. (When Melania floated the idea of calling her official anti-bullying platform “Be Best,” Wolkoff advised her against the name, telling her that it sounded “illiterate.”) A few days after the election, the Trumps tapped Wolkoff, who previously ran the Met ball with enough militaristic precision that it earned her the nickname “the general” around the Vogue office, to plan all the major events for the inauguration. Coming in with little political know-how, she had a matter of weeks to put together dozens of events with: a budget that kept shifting with little explanation; an inaugural chairman, Tom Barrack, and his deputy, Rick Gates, whom she felt were never fully above board with her; and an incoming first family that, for egotistical and business reasons, wanted their hands in all the planning, their company hosting a number of events, and their faces carefully arranged within the frame of all the historic moments that would be captured throughout that weekend.
