Russia may have withdrawn thousands of troops from Ukrainian border

After amassing tens of thousands of troops on its shared border with Ukraine, Russia may be pulling back at least some of their forces. The unconfirmed report comes from a Russian news agency, citing Russian military sources. However, a sizable force of up to 100,000 troops remain near the border. Daniel Treisman, a professor in the political science department at UCLA, joined CBSN's Elise Preston to discuss these latest developments.
