Jane Harman appeared on "Fox News Sunday" with columnist George Will, former Senator Rick Santorum and Time Magazine Assistant Managing Editor Rana Foroohar to discuss the crisis in Ukraine and US politics. 

"Vladimir Putin doesn't know the Colin Powell rule -- if you break it you own it. And if he breaks up Crimea, he's going to own their pension liabilities, their tanked economy, at a time when the Russian economy is stretched," Harman said.
