奥巴马：泄密事件显示国安局“重大薄弱环节”

U.S. President Barack Obama says the disclosure of the government's clandestine surveillance programs by a former intelligence contractor shows that there is a "pretty significant vulnerability" at the secretive National Security Agency.

But at a news conference Thursday in Senegal, the U.S. leader said he has no intention of "wheeling, dealing and trading" with foreign governments to secure the return of Edward Snowden to stand trial on espionage charges.

Snowden fled to Hong Kong and leaked details of two NSA programs that monitor telephone and Internet communications in the United States.  Later Snowden flew to Russia, where he is living in a transit zone at a Moscow airport while seeking asylum in Ecuador.

Mr. Obama said he had not called either Chinese President Xi Jinping or Russian President Vladimir Putin to request Snowden's extradition.  The president said he "should not have to" and the extradition request should be dealt with through "regular legal channels." 

He said, "This is something that routinely is dealt with between law enforcement officials in various countries."

Mr. Putin says Russia does not plan to extradite Snowden to the United States.
