WASHINGTON/SAN FRANCISCO: Twitter said on Thursday it had suspended about 200 Russian-linked accounts as it probes online efforts to meddle with the 2016 US election, but an influential Democratic senator slammed its steps as insufficient.
Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, summoned Twitter officials to testify behind closed doors on Thursday as part of broad investigation of Russian influence in the 2016 presidential election. Facebook faced a similar grilling earlier this month.
