Mark Warner, the senior United States Senator from Virginia, talks with Recode’s Kara Swisher and Peter Kafka at the 2018 Code Conference. Warner talks about the competing Senate and House reports on Russia’s use of tech platforms to meddle in the 2016 U.S. election. He also talks about the broader challenge of cybersecurity for policymakers, what has to be done to secure the 2018 midterms and what would prompt his fellow Democrats in Congress to impeach President Trump. Plus: Does cybersecurity need to be publicly funded like the military? And should American tech companies be regulated more?
