Microsoft President Brad Smith warned the danger of foreign interference in the U.S. election will surge in the final two days of the presidential campaign.

¡°The most perilous moment will come, I think, 48 hours before the election,¡± Smith told the Senate Intelligence Committee on Wednesday.

Smith said that was the ¡°lesson to be learned¡± from the Slovakian election last fall, in which fake audio of one of the top candidates circulated online days before the election.
