Countries offering asylum to NSA leaker Edward Snowden are taunting the U.S., top lawmakers said Sunday, and any country that eventually accepts Mr. Snowden should face economic reprisals from Washington.

The ultimate destination of Mr. Snowden remained in the air on Sunday, with Bolivia, Nicaragua, and Venezuela all apparently offering him a home, but no clear word yet on what Mr. Snowden might use for travel documents or if Russia would allow him to depart. He appears to remain inside the transit zone in Moscow’s international airport.
