WASHINGTON (Reuters) - More than two-thirds of the U.S. Senate approved on Wednesday Finland and Sweden's accession to NATO, the most significant expansion of the 30-member alliance since the 1990s as it faces the fallout from Russia's invasion of Ukraine.

As voting continued, the tally was 74 to 1, easily surpassing the two-thirds majority of 67 votes required to support ratification of the two countries' accession documents.
