Top Senate Intelligence Committee Democrat Mark Warner said Thursday he had “some concern” that Twitter had more than doubled the number of users it's notified about being exposed to the Russian election meddling campaign in 2016.

The other coast: Twitter said Wednesday that it notified 1.4 million people via email that they'd been exposed to Russian-linked election-related tweets. It had initially notified 677,775 people that they'd engaged with such content.
