CARACAS, Venezuela—A top official from Venezuela's electoral council says the audit of the vote from last Sunday's presidential election isn't about "revising" the outcome and warned against "false expectations."

Council Vice President Sandra Oblitas also said, however, that only the Supreme Court can change the outcome.

Her confusing appearance Saturday suggested difficulties ahead for opposition candidate Henrique Capriles. He claims the election was stolen by Hugo Chavez's chosen successor, Nicolas Maduro.

An audit of the 46 percent of the vote not scrutinized on election night is to begin next week. Official results gave Maduro a 260,000-vote victory of 14.9 million votes cast.

Inaugurated Friday, Maduro spent much of Saturday with the presidents of Nicaragua and Cuba. He tweeted that he discussed plans for the nation's future with them.
