Obama Says Allies in ‘Lockstep’ on Confronting Russia

President Barack Obama said the U.S. and its allies are in “lockstep” agreement on keeping up pressure on Russia over the crisis in Ukraine and the threat of broader economic sanctions hasn’t receded.

Obama, at a news conference in Brussels with U.K. Prime Minister David Cameron, also said the tensions with Russia highlight the need for the U.S. to work with European nations on energy security, so that Russia isn’t able to use its vast oil and gas reserves as a weapon.
