Twitter may notify users whether they were exposed to content generated by a suspected Russian propaganda service, a company executive told U.S. lawmakers on Wednesday.

The social media company is "working to identify and inform individually" its users who saw tweets during the 2016 U.S. presidential election produced by accounts tied to the Kremlin-linked Internet Research Army, Carlos Monje, Twitter's director of public policy, told the U.S. Senate Commerce, Science and Transportation Committee.

A Twitter spokeswoman did not immediately respond to a request for comment about plans to notify its users.
