The ads appear not to be from the same Russian trolls from the Internet Research Agency that advertised on Facebook. Google has launched an investigation into the ad-buying, which amounted to less than $100,000. Google did not comment on the matter to the Post, which cited people familiar with the company's investigation.

An individual familiar with the investigation tells CBS News that so far Google has identified some $4,700 worth of ads thought to be connected to the Russian government or people working on behalf of the Russians.

Digging deeper, the investigation also identified over $50,000 of political type ads bought from Russian affiliated web sites or paid for in rubles. Those ads have not been clearly tied back to the Russian government.
