MOUNTAIN VIEW, CA — Google, which is still deciding whether to join Facebook and Twitter in testifying before Congress next month about Russian election meddling, discovered that Russian operatives did, in fact, buy tens of thousands of dollars in ads across the Silicon Valley titan's products, including Google search, YouTube and Gmail, The Washington Post reported.

The revelations came to light after Google siphoned off a trove of data from Twitter, the report said citing anonymous sources familiar with the investigation. Twitter gives away a small amount of historical tweets for free, but developers can pay to access all of the data dating to 2006, the report said.

"Google downloaded the data from Twitter and was able to link Russian Twitter accounts to other accounts that had used Google's services to buy ads," the report said. This was apparently done without Twitter's "explicit cooperation," the report said.
