ROCHESTER, Minn. - CBS reports Facebook is adding a tool that will tell users if they liked pages linked to fake Russian pages.
The tool is supposedly under the Help Center tab on users' home page.
In October, Facebook told the Senate Judiciary Committee the fake pages were "delivered" to about 29 million people. After more activity on the site, the content could have been seen to as many as 129 million users.
