Thankfully the citizens of the United States of America will not have to pay Trump's legal fees because Washington DC and Maryland are suing Trump as a private citizen
"Maryland Attorney General Brian Frosh says that he and D.C. Attorney General Karl Racine are suing Trump as a private citizen.
A lawsuit filed by D.C. and Maryland against President Trump over his alleged business conflicts has been expanded to include Trump in his personal capacity as a businessman, which means that a summons has been sent to perhaps the most famous address in Washington: 1600 Pennsylvania Avenue.
The attorneys general for both states argue in a lawsuit that Trump is violating the emoluments clause of the U.S. Constitution, which in part bans public officials from receiving gifts and payments from foreign governments without approval from Congress."
