Biden to Putin: 'Don't Tells Us, Show Us'

"Too many times, President Putin has promised peace and delivered tanks and troops and weapons. So we will continue to provide Ukraine with security assistance, not to encourage war, but to allow Ukraine to defend itself," Biden said. Biden and Secretary of State John Kerry met Saturday with Ukrainian President Petro Poroshenko and German Chancellor Angela Merkel, who on Friday traveled to Moscow with French President Francois Hollande to meet with Putin and propose a new peace plan.
