Close to one year after Donald Trump’s election as President of the United States, the role of Russia in the process continues to be a subject of discourse.

Probes have been launched and internet giants are expected to tell Congress this week that Russian-backed content aimed at manipulating US politics during last year's election was more extensive than previously thought.

Facebook, Google and Twitter are slated to share what they have learned so far from digging into possible connections between Russian entities and posts, ads, and even videos shared on YouTube.

Facebook will tell Congress that some 126 million US users, a potentially large portion of the voting public in America, may have seen stories, posts or other content from Russian sources, according to tech news site Recode, the Wall Street Journal and other US media.

Google found that two accounts linked to the Internet Research Agency spent $4,700 on search and display ads during last year's US election cycle, Google general counsel Kent Walker and director of information security Richard Salgado said in a blog post.

"Like other internet platforms, we have found some evidence of efforts to misuse our platforms during the 2016 US election by actors linked to the Internet Research Agency in Russia," Walker and Salgado said.
