Evidence against Russia is mounting as the U.S. and Ukraine accuse Moscow of moving heavy artillery across the border of Ukraine to pro-Russian rebels.

Rep. Peter King (R-N.Y.) said today on "Sunday Morning Futures" that we should send weapons to Ukrainians and implement heavy economic sanctions. He also said our European allies must stand together, but Europe is afraid of being cut off from Russia's energy supply. King said Obama must show real leadership now.

“President Obama is just missing in action on this,” he said.
