VAUSE: Very big tech companies, Twitter, Facebook, and Microsoft have identified and are now removing fake and malicious content. Twitter announced it has removed hundreds of accounts for "engaging in coordinated manipulation." Many accounts originated in Iran and Twitter is now working with law enforcement, as well as other companies, to try to fix the problem. Facebook says it's removed 652 pages of accounts or groups that were part of a coordinated disinformation campaign. Some of the pages originated also in Iran but also Russia. And Facebook says these pages were spreading misinformation not only in the United States, but also in the U.K., Latin America, and the Middle East, all posing as a group called Liberty Front Press. Meantime, Microsoft has taken control of six phony websites created by hackers tied to Russian military intelligence. The sites were apparently designed to fool users into thinking they belonged to two U.S. based Conservative think tanks and the U.S. Senate. It's just the latest evidence that Russia's attempt to interfere in U.S. politics did not end with the 2016 presidential election.</s>BRAD SMITH, PRESIDENT, MICROSOFT: We have no doubt in our minds that these six websites were set up by this group called</s>VAUSE: As far as the kremlin's concerned, they didn't do it.
