Russia threatens retaliation after Twitter bans adverts from RT and Sputnik news outlets

Twitter has has banned two Russian media outlets from advertising on the social network after concluding that they colluded with the Kremlin to influence the US election. Russia Today (RT) and Sputnik, which have spent a combined $1.9 million on Twitter adverts, were blacklisted after an internal investigation into the two, following US intelligence reports saying they were part of a Russian effort to disrupt 2016’s vote. The decision prompted a furious response from the two news outlets, which are funded by the Russian government and seen as its mouthpieces in the West.
