President Barack Obama raised Friday, U.S. concerns directly with Russian President Vladimir Putin on Friday over Moscow's handling of former U.S. spy agency contractor Edward Snowden, but there was no sign of a breakthrough on Washington's demand that Russia expel him to face espionage charges at home. Snowden has applied for temporary political asylum in Russia. A White House statement about the Obama-Putin call offered no indication that Putin was prepared to send Snowden back to the United States.
