The United States announced on Thursday it was imposing sanctions on 16 Venezuelan government officials appointed by the country’s autocratic president, Nicolás Maduro, in response to the disputed presidential election on July 28.

The past year saw months of repression leading up to the election, which was followed by a brutal crackdown in response to international and national criticism of the results.

On Election Day Mr. Maduro claimed victory without releasing a breakdown of results. He has yet to do so. The opposition has published thousands of receipts from voting stations, representing over 80 percent of the vote, showing that their candidate Edmundo González won by a wide margin.

A senior U.S. administration official, in a call with journalists on Thursday, said it was clear that Mr. González had won more votes and that Mr. Maduro’s government was denying that fact and trying to cling to power at all costs.

According to the conditions of the call, the official discussing the Biden administration’s actions could not be named in order to discuss sensitive diplomatic matters.

Who is being sanctioned?

The list includes officials from the country’s electoral authority and supreme court, justice system, legislature and security forces. They are now added to a list of hundreds of Venezuelan officials who have been sanctioned by the Treasury Department in recent years, including Mr. Maduro.
