Two former Salvadoran presidents - Mauricio Funes, who served from 2009 to 2014, and his successor Salvador Sanchez, whom Washington links to corruption, money laundering and embezzlement of public funds - were added to the list.
Guatemala's government meanwhile rejected the accusations on Wednesday, labeling the report "used by the United States to impose its jurisdiction on people abroad, as despicable."
It includes ex-officials from the government of former Honduran President Juan Orlando Hernandez, who was extradited to the United States over drug trafficking links.
Politicians from Honduras' opposition Liberal Party also appear, including Liberal leader Yani Rosenthal, previously convicted of money laundering in the United States.
The Nicaraguan section includes all of the country's parliamentary leaders, barring its president, who Washington has already sanctioned, and several judges and directors of Nicaragua's money laundering watchdog.
