Snowden is charged with violating American espionage laws by leaking secret documents.
Ecuador's President, Rafael Correa, announced Saturday he had a "friendly" conversation with Vice President Biden Friday. He said he cannot consider the asylum request until Snowden is actually on Ecuadorian soil.
The U.S. believes Snowden is holed up in a Russian airport's transit zone waiting to see if any country will protect him from extradition.
