Senator calls Twitter's explanation of Russia-linked accounts 'frankly inadequate'

Twitter told congressional investigators it has suspended at least two dozen accounts that may have been tied to Russia, but the information shared by the social media giant at the briefing was described as "frankly inadequate".

Virginia Senator Mark Warner said Twitter's explanations of its actions against Russia-linked accounts were "deeply disappointing", and he suggested the company does not understand the seriousness of Congress' investigation into Russian interference in the 2016 election.
