Microsoft President Brad Smith cautioned U.S. lawmakers about heightened foreign interference threats in the last 48 hours before the November 5 presidential election. During a Senate Intelligence Committee hearing, he highlighted the lessons learned from Slovakia's recent election, where disinformation tactics were employed. Smith noted that adversarial countries, notably Russia and Iran, are spreading manipulated content targeting candidates Vice President Kamala Harris and former President Donald Trump. He specifically mentioned an AI-enhanced video from Russia that misrepresented Harris at a campaign rally. The hearing included testimonies from other tech leaders, such as those from Google and Meta, while representatives from TikTok and Twitter were absent. The overarching concern is the impact of emerging technologies on the integrity of electoral processes.
