Two of the businessmen included Jose Manuel Gonzalez Testino (Gonzalez), a dual U.S.-Venezuelan citizen, and Tulio Anibal Farias Perez (Farias), a Venezuelan national and Houston resident.
De Jongh admitted to directing bribe payments from Gonzalez and Farias and others into bank accounts in the names of shell companies he controlled in Panama and Switzerland.
De Jongh laundered the bribe proceeds through U.S. and international bank accounts and used the funds to purchase real property located in the Houston area.
De Jongh pleaded guilty on Monday to one count of conspiracy to commit money laundering.
As part of his plea, De Jongh also agreed to forfeit over $3 million seized from his bank accounts and 15 properties he purchased with his corrupt proceeds.
