President Joe Biden said Tuesday that the U.S. will begin to impose sanctions on Russia, calling recent troop movement into Ukraine an 'invasion.' Biden and other government officials including from the State Department have begun to classify the Russian troop movement as an invasion after Russian President Vladimir Putin ordered troops to two independent Ukrainian areas in an alleged "peacekeeping" mission — which the West considers an act of aggression. Biden said Russia will continue to pay 'an even steeper price' if it continues sending troops into Ukraine. What happens next? Will Putin find a way around these sanctions? Ariel Cohen, senior fellow at the Atlantic Council, joins Closing Bell to discuss Biden's remarks, how the West will protect Ukraine since it doesn't belong to NATO, and more.
