Recode Decode, Hosted By Kara Swisher

Mark Warner, the senior US Senator from Virginia, talks with Recode's Kara Swisher about several interconnected policy issues affecting the 2020 elections, including the security of voter registries, the expectation of social media manipulation by Russia and other hostile foreign powers, and the newly announced impeachment inquiry into President Trump's phone call with Ukrainian president Volodymyr Zelensky. Sen. Warner also talks about the potential of regulators breaking up tech giants and how the US government's relationship with those companies has improved since 2016, yet still calls for more oversight of their unprecedented power. Plus: Why he's "cautiously optimistic" about Republicans in the Senate embracing election reform and new privacy laws, his proposal for incentivizing companies to invest in their workers, and how Warner thinks Congress might be able to fix Section 230 of the Communications Decency Act without repealing it wholesale.
