Washington (CNN) The Trump administration imposed sanctions on Venezuelan President Nicolas Maduro's wife and three other members of his inner circle.

On Tuesday, the Treasury Department announced new sanctions against Cilia Adela Flores de Maduro, the former attorney general and President of the National Assembly.

Delcy Rodriguez, the executive vice president of Venezuela and Jorge Rodriguez, the minister of popular power for communication and information, and Vladimir Padrino, the defense minister also were also sanctioned by the US government.

"We are continuing to designate loyalists who enable Maduro to solidify his hold on the military and the government while the Venezuelan people suffer," said Treasury Secretary Steven Mnuchin said in a statement.
