Venezuelan President Nicolas Maduro has called for a vote on Sunday that Trump and many other critics say will transform the South American government into dictatorship.
The opposition vowed to protest through the weekend, raising the spectre of further violence given that the government has banned protests from Friday to Tuesday. The delegates - majority expected to be ruling-party loyalists - would have the power to rewrite the 1999 constitution, dissolve other branches of government, and call and cancel future elections.
At least seven of those deaths happened Wednesday and Thursday during a two-day opposition-led general strike. But the hundreds of thousands who have sometimes taken to the streets during almost four months of anti-government protests were largely absent.
Despite the US sanctions and calls from countries including Canada to cancel Sunday's vote, the Maduro regime has shown no signs of backing down.
Venezuelan President Nicolas Maduro has said the vote is a chance to bring unity and peace to the country. "The constituent assembly lacks legitimacy and because of that we can not accept the result،" he said. Protesters say the election of a constitutional assembly will allow Maduro to eliminate democratic checks and balances and install an authoritarian single-party system.
The U.S. also said it had determined that Venezuelan Vice President Tareck El Aissami, hit with U.S. sanctions in February, had "hundreds of millions of dollars" in assets that have been frozen due to the sanctions. His finance minister also told a local radio station the neighboring nation would sanction the same 13 former and current Venezuelan officials cited by the US on Wednesday.
But Maduro called for the constitutional revisions, and with pro-Maduro candidates running for numerous seats, including former ministers in his government, the body is likely to favor him. Protesters are planning to expand their demonstrations, and officials are anxious those protests could turn violent.

Prior to the general ban on public assembly, a Miami Herald report unveiled that Maduro had attempted to convince the opposition to "cool down" protests in exchange for postponing the vote on Sunday through Spanish socialist José Luis Rodríguez Zapatero, who has previously acted as a mediator for the regime. As of late Friday, few appeared to have heeded the calls.
