But a close read of the document requests suggests they aren’t exactly tiptoeing around the first daughter, either.

Of the 81 document requests sent, 52 individuals and organizations were asked to turn over documents related to Ms. Trump or her business interests.

White House officials are viewing the document requests as an attempt by the House Judiciary Committee to set the stage for potentially impeaching the president. But the inquiries related to Ms. Trump follow a side track: They ask for documents related to any financial benefit that Ms. Trump or her businesses reaped from foreign and domestic governments after the 2016 election. And they provide a hint of how Representative Jerrold Nadler of New York, chairman of the House Judiciary Committee, may be planning to look into potential financial conflicts of interest from Ms. Trump.

“She’d be in violation of the Constitution if she was getting any business deals from foreign governments,” said Richard W. Painter, who served as chief ethics lawyer under President George W. Bush. Mr. Painter was referring to the emoluments clause of the Constitution, which prohibits government officials from accepting payments or gifts from foreign governments.

“They’re also going after other payments that aren’t emoluments clause violations that we ought to know about that could be creating financial conflicts of interest for her,” Mr. Painter said. “The idea here is to get an awful lot of information we would have had if there had been more detailed disclosures about the entities the Trump family controls.”
