Washington DC - The White House on Thursday walked back an earlier call by President Joe Biden for new elections in Venezuela, saying he was actually just pointing out the "absurdity" of Nicolás Maduro's claim of election victory.

"The president was speaking to the absurdity of Maduro and his representatives not coming clean about the July 28 elections," a White House spokesman said, adding that it was "abundantly clear" that opposition candidate Edmundo Gonzalez Urrutia had won.

Asked by a reporter at the White House whether he supported a repeat of Venezuela's controversial election – in line with calls Thursday by the presidents of Brazil and Colombia – Biden clearly replied, "I do."

However, the National Security Council soon after indicated that Biden had only been making a general statement about the US position on Venezuela.

"It is abundantly clear to the majority of the Venezuelan people, the United States, and a growing number of countries that Edmundo Gonzalez Urrutia won the most votes on July 28," an NSC spokesman said.

"The United States again calls for the will of the Venezuelan people to be respected and for discussions to begin on a transition back to democratic norms."

Maduro's July 28 win continues to be disputed, with the US – which has fiercely opposed Venezuela's socialist party since it first gained power in 2007 – backing Urrutia's as yet unproven claims of a landslide victory.
