FILE - This Feb. 7, 2014 file photo shows Defense Secretary Chuck Hagel holds a briefing at the Pentagon. The U.S. will send medical supplies, helmets and other non-lethal aid to the Ukrainian military in response to Russia’s “dangerously irresponsible” efforts to destabilize the country, Hagel said Thursday. Hagel told a Pentagon news conference that he telephoned Ukraine’s acting defense minister to tell him that President Barack Obama had approved the assistance, which does not include weapons. Hagel said the Obama administration will “continue to review” additional aid requested by Ukraine. (AP Photo/Susan Walsh, File)
