Putin Signs Treaty to Annex Crimea

Russia's President Vladimir Putin claimed Crimea as part of Russia today, brushing aside international condemnation. Vice President Joe Biden denounced the action during a visit to Poland. "Unfortunately Russia's leaders have responded with a brazen, brazen military incursion, with a rushed and illegal referendum in Crimea – that was not surprisingly rejected by virtually the entire world – and now today with steps to annex Crimea." Ellen Barry is reporting from Moscow for the New York Times.
