emolument

If a federal judge lets the plaintiffs proceed with their lawsuit against the president, the next step would give them access to some of his financial documents — perhaps including tax returns.

On Wednesday, a federal judge will hear arguments in a case that asks: Is President Trump taking the kind of benefits banned by the Constitution? Step 1 is deciding whether plaintiffs have standing.

The group filing the suit says it is asking a federal court "to stop President Trump from violating the Constitution by illegally receiving payments from foreign governments."

A legal debate is heating up around a provision called the Emoluments Clause. Experts are examining whether Trump can legally continue dealing with companies controlled by foreign governments.
