'More united' -Biden signs support for Sweden, Finland to join NATO

STORY: Biden signed the U.S. "instrument of ratification" welcoming the two countries, the final step for their endorsement by the United States.

The U.S. Senate backed the expansion by an overwhelming 95-1 last week, a rare display of bipartisan unity in a bitterly divided Washington. Both Democratic and Republican Senators strongly approved membership for the two Nordic countries, describing them as important allies whose modern militaries already worked closely with NATO.

Sweden and Finland applied for NATO membership in response to Russia's Feb. 24 invasion of Ukraine. Moscow has repeatedly warned both countries against joining the alliance.

Putin is getting "exactly what he did not want," with the two countries entry into the alliance, Biden said.
