Kerry: "Serious consequences" if Snowden allowed to board a plane

(CBS News) The White House is not happy about National Security Agency leaker Edward Snowden's travels, putting out a blistering statement overnight, about the lack of cooperation from other countries.

The White House has tried hard to put pressure on the other countries involved to send Snowden to the U.S. -- to not let him go on to Havana or Ecuador. CBS News has learned that the U.S. government has been in contact with Cuba, CBS News' Bill Plante reported. A National Security Council spokesperson says also that the U.S. expects the Russians to cooperate, given the fact that the U.S. has returned criminals whom the Russians wanted.

Secretary of State John Kerry said Monday there would be "serious consequences" if Snowden is allowed to board a plane and leave Moscow.

Washington was caught very much by surprise when the Hong Kong government, with the apparent agreement of China, allowed Snowden to depart on Sunday, and has registered its deep displeasure. But the move comes as Chinese has seized on Snowden's charges that the U.S. has spied extensively on computer traffic in both Hong Kong and China.

In the meantime, White House officials say that the president has been updated regularly on Snowden's status. Officials here remain extremely concerned. There's a real sense of urgency about this because they don't know how much more classified material Snowden has in his possession.

And senior officials are very dismissive of Snowden's claim that he's advancing transparency and free speech by releasing U.S. secrets. They say that by choosing China, Russia, Ecuador and Venezuela as his protectors, his motive seems to be to injure the United States' national security.
