Sarah Harrison, a WikiLeaks representative, is reportedly traveling with Edward Snowden, the National Security Agency leaker. Russia’s Interfax news agency reported she and Snowden were in Moscow’s Sheremetyevo International Airport, waiting for a flight to Cuba.

Harrison is the closest adviser to WikiLeaks’ Julian Assange, its editor-in-chief and founder. WikiLeaks confirmed on its website that Harrison was instrumental in Snowden’s departure from Hong Kong: “Miss Harrison has courageously assisted Mr. Snowden with his lawful departure from Hong and is accompanying Mr. Snowden in his passage to safety.”

Harrison, a U.K. citizen, is a journalist and legal researcher who works with the WikiLeaks Legal Defense team, which is led by former Spanish Judge Baltasar Garzon. According to her WikiLeaks profile, Harrison has worked on past projects related to human-rights violations, global surveillance and security. She is a WikiLeaks section editor and an investigative researcher for both the Bureau of Investigative Journalism and the Center for Investigative Journalism.

Snowden landed at Moscow’s Sheremetyevo airport Sunday after leaving Hong Kong. Media outlets are reporting Snowden will fly first from Russia to Cuba, and then from there to Venezuela. However, Ecuadorian diplomatic vehicles were spotted at the airport, suggesting that Ecuador could in fact be Snowden’s final destination, especially as he has applied for asylum there, according to Reuters.
