BOGOTA, Colombia - Vice President Joe Biden called Ecuadorean President Rafael Correa and asked him to reject the asylum plea of Edward Snowden, the fugitive NSA leaker.

During his regular Saturday television program, Correa said the conversation was "polite" and that Biden had asked him to reject Snowden's request "as a favor."

Correa, 50, said the country cannot begin processing the plea until Snowden - who is reportedly in the transit zone of a Moscow airport - is on Ecuadorean soil.

He also said he brought up the case of Roberto and William Isaias, two brothers convicted in Ecuador of embezzling more than $660 million during the country's 1999 banking crisis. Both men live in Miami, and Ecuador says it has repeatedly asked for their extradition. The men have long rejected the charges, saying they were victims of the country's financial crisis.

Biden "told me that Mr. Snowden was a fugitive of American justice and didn't have a passport," Correa said, according to El Telegrafo newspaper. "I told him, 'Well, the Isaiases are fugitives of Ecuadorean justice, and they also don't have passports and you won't extradite them.' "

Unlike Snowden, who is wanted on various crimes under the espionage act, the Isaias brothers "have already been convicted," Correa said.

National Security Council spokeswoman Bernadette Meehan said the conversation took place Friday.

"They engaged in a broad conversation regarding the bilateral relationship," she said in a statement. "They did discuss Mr. Snowden, but we are not going to provide details on their discussion."

Snowden, a former CIA employee and National Security Agency contractor, has eluded U.S. authorities who want to prosecute him for revealing secret surveillance programs that monitored Internet and telephone communications worldwide. The United States revoked his passport, and Ecuador has denied reports that it provided him with valid travel documents.

On Saturday, Correa accused the international media of trying to demonize his country and losing sight of Snowden's claims.

"What's important here is what Snowden has revealed: the largest mass spying program in the history of humanity, inside and outside of the United States," Correa said.
