U.S. President Barack Obama confirmed on Tuesday that he would go to Russia this fall for a G20 summit but expressed disappointment that Russia had granted temporary asylum to former government contractor Edward Snowden.
Speaking on NBC's "The Tonight Show" with host Jay Leno, Obama said Moscow sometimes still slips into a Cold War mentality. He did not mention whether he would attend a separate one-on-one meeting with Russian President Vladimir Putin. The White House has said it is evaluating whether that meeting makes sense.
During the interview, Obama also said the recent threat that caused the United States to close embassies throughout the Middle East was significant.
"It's a reminder that for all the progress we've made ... this radical, violent extremism is still out there," Obama said. "We've got to stay on top of it."
