White House "appalled" by Ukraine violence
White House Press Secretary Jay Carney says the Obama administration is "appalled" by the violence in Ukraine.
For the time being, President Barack Obama has assigned the Ukraine problem to Vice President Biden, CBS News chief White House correspondent Major Garrett reported from Toluca, Mexico, where the president will travel Wednesday for a summit.
Biden has called Ukrainian President Vicktor Yanukovich three times since Jan. 23, with the same message each time -- government forces must pull back and de-escalate tensions that have led to violence.
The U.S. and European countries are now actively considering tougher economic sanctions -- a message Biden delivered by phone to Yanukovich Tuesday.
President Obama arrives in Toluca Wednesday and is not expected to address Ukraine in his opening summit remarks, preferring to focus on trade, investment and energy talks with his counterparts from Mexico and Canada.
