WASHINGTON (AP) — The chairman of the Joint Chiefs of Staff says NSA leaker Edward Snowden's disclosures about U.S. surveillance programs have undermined U.S. relationships with other countries and affected what he calls "the importance of trust." Gen. Martin Dempsey tells CNN's "State of the Union" that the U.S. will "work our way back. But it has set us back temporarily." Russian officials say Snowden has been stuck in the transit area of a Moscow airport since arriving on a flight from Hong Kong two weeks ago. Venezuela, Bolivia and Nicaragua have offered asylum. House Intelligence Committee Chairman Mike Rogers tells CNN that the U.S. should look at trade agreements with any nation that offers asylum "to send a very clear message that we won't put up with this kind of behavior."
