WASHINGTON (AP) — Republican senators said Wednesday that the government faces a momentous task in preventing foreigners from using social media to interfere in U.S. elections, citing concerns about the First Amendment and the sprawling nature of the internet.

Experts testifying before the Senate Intelligence Committee said Russia and other foreign actors are using high-tech means to polarize Americans not only on elections, but also on highly charged issues like race and immigration. The hearing came one day after Facebook said it had uncovered new sophisticated efforts, possibly linked to Russia, to manipulate U.S. politics ahead of the midterm elections.
