The New York Attorney General's office does.
New York attorney general's office deposing Eric Trump in tax investigationEric Trump had initially attempted to delay the deposition until after Election Day, citing a busy campaigning schedule, but New York Supreme Court Judge Arthur Engoron ordered him to comply with the subpoena, stating that he did not have the authority to push back the date and that the court had no reason to work around Election Day.
The assets in question include at least four properties. One is the Seven Springs estate once owned by Washington Post publisher Eugene Meyer. The New York attorney general's office began the investigation last March when President Trump's former attorney Michael Cohen alleged in his congressional testimony that his ex-boss had regularly inflated the value of his assets.
Along with Eric Trump's deposition, documents related to the value of these assets that had previously been withheld were also requested. Any documents obtained during the probe remain sealed.
