Follow online: The Information and Politico Pro are partnering to do a “flash briefing” as a conference call at 4:30 PM ET on Wednesday (while the House hearing is still going on). It will be hosted by The Information founder and editor-in-chief Jessica Lessin and will feature Nancy Scola, Politico Pro senior technology reporter, and The Information reporter Cory Weinberg. “They will detail how each hearing will impact legislation, including the Honest Ads Act, as well as provide the latest intelligence about possible connections to the Trump and Clinton campaigns, and outline how tech giants like Facebook and Google are responding to Russian propaganda arms like RT and political pressures of the current environment,” a Politico spokesperson said. The Information subscribers will receive a dial-in for the call 30 minutes before it starts; if you want to listen and aren’t already a subscriber, there’s a trial offer right now that’s $1 per month for the first three months.
