WASHINGTON (Reuters) - U.S. lawmakers demanded that technology firms do more to fight "shocking" foreign efforts to influence U.S. politics on Wednesday, a day after Facebook Inc identified a new influence campaign tied to November's elections and despite President Donald Trump's denunciation of the issue as a "hoax."
The Senate Intelligence Committee has called executives of Facebook, Twitter Inc and Alphabet Inc's Google to testify on Sept. 5 "to hear the plans they have in place, to press them to do more, and to work together to address this challenge," Senator Mark Warner, the panel's Democratic vice chairman, said at a hearing.
