According to The Washington Post , the suit alleges that Trump violated constitutional anti-corruption clauses by taking payments from foreign governments while in office. The Post says the lawsuit centers on Trump retaining ownership of his company when he became president.

Trump said he was shifting assets into a trust managed by his sons to eliminate potential conflicts of interest.
