The Trump administration imposed sanctions Friday on four Venezuelan officials, accusing them of engaging in political repression and public corruption as part of President Nicolás Maduro’s government.

One official, a sitting governor, had served as head of the food ministry, which has been blamed for mismanaging a program critical in a nation where children have died of hunger. Another, a former governor, was said to have empowered armed gangs in Bolívar State.

“President Maduro and his inner circle continue to put their own interests above those of the Venezuelan people,” Treasury Secretary Steven Mnuchin said in a statement. “This action underscores the United States’ resolve to hold Maduro and others engaged in corruption in Venezuela accountable.”

In announcing the sanctions, the Treasury Department criticized Venezuela’s all-powerful National Constituent Assembly — which the United States considers “illegitimate” — for effectively stripping the three biggest opposition parties of their ability to participate in the next presidential election, which is supposed to take place this year. The assembly has decreed that only parties that took part in the previous election will be eligible.
