RIO DE JANEIRO (AP) — Edward Snowden is offering his services to Brazil.

One of the country's biggest newspapers has published an open letter from the National Security Agency leaker saying he would be willing to help Brazil's government investigate U.S. spying on its soil, as long as he's granted political asylum.

Brazilian senators have asked for Snowden's help during hearings about the NSA's aggressive targeting of Brazil, which serves as a hub for trans-Atlantic fiber optic cables.
