Investigators will look at YouTube and Gmail in the Russia inquiry

In addition to Facebook and YouTube, Google will also be scrutinized by investigators in relation to the Russia inquiry. All three companies are expected to testify to congress on November 1, as previously reported.

In Google's case, investigators will focus on a variety of services the company makes, especially YouTube and Gmail, Bloomberg first reported.

Google began an internal review of any potential abuse from Russian actors last week, the Bloomberg report says. A Google spokesperson confirmed to Business Insider that the company removed the Kremlin-run news organization Russia Today (RT) from its Google Preferred network. Google Preferred connects content creators with higher-paying advertisers. The move comes after increasing concerns over a January report from the Director of National Intelligence that linked RT to Russia's attempts to undermine the 2016 US election.

However, RT still exists on YouTube. Some view RT as more like state-run news organizations like BBC or Al Jazeera, not necessarily shady anonymous actors trying to game internet platforms. Twitter said last week that it found ads from RT on the service.

The Bloomberg report also says investigators will look at Gmail, after John Podesta's personal account was broken into last year.

The Google spokesperson declined to comment on the rest of the Bloomberg report.
