MELBOURNE (Reuters) - U.S. Senator John McCain said Russian President Vladimir Putin is a bigger threat to global security than ISIS, and warned that the Senate would push for sanctions against Moscow for its alleged interference in the U.S. election.

McCain, a leading foreign policy voice in the U.S. Congress, was speaking in an interview in Australia, where he has held security talks on his way to a defence summit in Singapore.
