NSA whistleblower Edward Snowden is “considering’ returning to the United States if certain conditions are met, his lawyer told Germany’s Der Spiegel.

“There are negotiations,” Snowden’s German lawyer Wolfgang Kaleck said, according to a translation on RT.com, a news agency based in Russia. “Those who know the case are aware that an amicable agreement with the U.S. authorities will be most reasonable,” Kaleck said.

Snowden is not involved in the negotations, Kaleck told Der Spiegel.
