In the subpoena, investigators also showed interest in whether any foreigners illegally donated to the committee, as well as whether committee staff members knew that such donations were illegal, asking for documents laying out legal requirements for donations. Federal law prohibits foreign contributions to federal campaigns, political action committees and inaugural funds.
Prosecutors also requested all documents related to vendors and contractors with the inaugural committee, which raised a record $107 million and spent lavishly.
People familiar with the subpoena said prosecutors are interested in potential money laundering as well as election fraud, though it is possible that the prosecutors do not suspect the inaugural committee of such violations. The prosecutors cited those crimes in the subpoena simply as justification for their demand for documents, the people said.
Only one individual was named as part of the subpoena’s demand for documents: Imaad Zuberi, a former fund-raiser for President Barack Obama and Hillary Clinton who was seeking inroads with Mr. Trump, and whose company, Avenue Ventures, gave $900,000 to the inaugural committee. The subpoena also seeks documents related to his company.
