Biden, Putin to Hold Conversation on Rising Tension Between Russia, Ukraine

President Joe Biden and Russian President Vladmir Putin are expected to have another conversation surrounding escalating tensions between Russia and Ukraine. Ariel Cohen, senior fellow at the Atlantic Council, joined Cheddar's Ken Buffa to discuss the ongoing tensions and why Putin's request for a conversation with Biden comes now. "This is very serious. This is the worst security crisis we had since the collapse of the Soviet Union," Cohen told Cheddar.
