Transcript for White House Issues New Tough Sanctions on Russia
today, president Obama issued a new challenge to Russian president Vladimir Putin. More tough sanctions, in partnership with Europe. And the big question is, will Putin feel the pressure this time? Let's bring in ABC's chief white house correspondent, Jonathan Karl. What is the answer, Jon? Reporter: Well, Diane, these sanctions will sting. They go right at the lifeline of the Russian company, hitting the energy, banking and defense sectors. It's a move that comes 12 days after the downing of Malaysian flight 17, as president Obama announced the moves, he made it clear that his aim is to make Russia and Vladimir Putin in particular pay a high price for supporting the pro-russian rebels that shot that plane down. It doesn't have to come to this. It didn't have to come to this. It does not have to be this way. This is a choice that Russia and president Putin in particular has made. Reporter: Nothing in Putin's behavior suggests that any of this will change his course. Certainly nothing has changed it so far. But white house officials, Diane, say these are the toughest actions taken by the United States and Europe against Russia so far. All right, Jonathan Karl reporting on it all from the white house tonight. Thanks, Jon.
