Congress is advancing sanctions against Russia or any other country offering asylum to whistle-blower Edward Snowden.

The measure introduced by Republican Sen. Lindsey Graham demands the State Department coordinate with lawmakers on setting penalties against nations that seek to help Mr Snowden avoid extradition to the United States.

Venezuela, Bolivia and Nicaragua have offered Mr Snowden asylum since he revealed details of the U.S. government’s massive surveillance programme. He has been stuck in Moscow’s airport but may soon be allowed to leave. He has yet to gain asylum in Russia.

The Senate Appropriations Committee approved Graham’s measure unanimously by voice vote Thursday after it was included as an amendment to next year’s foreign operations bill.
