Tehran (CNN) -- Iranian TV aired images Thursday of what it says is a U.S. stealth drone that went down in Iran last week, an apparently intact RQ-170 drone propped on a pedestal and triumphantly displayed. "Military experts are well aware how precious the technological information of this drone is," said Brig. Gen. Amir Ali Hajizadeh, commander of the Islamic Revolutionary Guards Corps Aerospace Forces, according to the semi-official Fars News Agency. There was disagreement among Pentagon officials about whether the drone in the video is real. Military and intelligence officials were analyzing the Iran television footage. One U.S. official said right now the U.S. can't be certain it's the real stealth drone, because U.S. personnel don't have access to it. But he added there's no reason to think it's a fake.U.S. official: "We now have no reason to believe" the drone in the video is a fakeAnother official questions the intact appearance of the drone after a crashAn Iranian general says the drone was downed "with minimum damage"Iran's Foreign Ministry delivers a reprimand of U.S. to Swiss envoy

Washington (CNN) Sen. Elizabeth Warren delivered an unsubtle criticism of former President Barack Obama in an interview published Monday, saying the former president and other politicians are out of touch with "the lived experiences of most Americans."

(CNN) Every day we learn more about the scale and effectiveness of Russian influence operations during the 2016 US election. The implications for our political process are ominous, but the problem runs much deeper. For years hostile foreign governments, terrorist groups, and armies of internet trolls have manipulated public discussion, both in the United States and around the world. We must understand Russia's manipulative attack during last year's presidential elections in a broader context: as a relatively traditional propaganda operation that achieved unprecedented reach because social media companies are either unable or choose not to defend themselves. Every time our society falls victim to an information attack, we blame the attacker, but not their weapons. It's hard to accept that the platforms we use to chat with friends and share baby photos can have such a powerful impact in shaping democracy. Platforms like Google, Facebook, and Twitter have fundamental flaws that must be fixed if we're going to protect ourselves in the future.Jonathon Morgan: For years hostile governments, terrorist groups, and internet trolls have manipulated public discussionSocial media and government have to take steps to prevent this, Morgan says
