WASHINGTON — The Trump administration is considering imposing sanctions on additional Venezuelan officials, one of several options under discussion as a rebuke to President Nicolás Maduro’s government and his efforts to consolidate authority.

Administration officials said they were using a number of tactics to persuade Mr. Maduro to hold off on constituent assembly elections seen by critics as a power grab, and more broadly to ease the authoritarian tilt of his government.

They stressed that the Trump administration was talking to other governments about how best to proceed. But they said they reserved the right to engage in unilateral actions, if need be.

A senior Trump administration official declined in a conference call with reporters on Tuesday to name the potential targets of sanctions. But the announcement came two days after an unusual election organized by opposition parties in Venezuela, in which more than seven million people cast votes to express their disapproval of Mr. Maduro. The government says that vote is illegitimate.
