The Obama administration is rejecting calls to grant clemency to National Security Agency leaker Edward Snowden just days after Snowden asked for international help. In a letter given to a German lawmaker last week, Snowden called on the United States to drop charges against him, writing: “Speaking the truth is not a crime.” On Sunday, White House senior adviser Dan Pfeiffer ruled out clemency and said Snowden should return to face criminal charges. In some of the latest of Snowden’s disclosures, The New York Times reports the NSA intercepted the talking points of U.N. Secretary-General Ban Ki-moon ahead of a meeting with President Obama in April. The NSA also mounted a major eavesdropping effort focused on the United Nations climate change conference in Bali in 2007.
