Silicon Valley's most prominent companies are running a gauntlet in Washington this week: top staffers from Facebook, Google and Twitter will be confronted by three Congressional panels on Tuesday and Wednesday about the role their platforms played in Russian election meddling.

  • Expect Democrats to push especially hard — with questions not just about the Russian advertisements that have dominated discussion so far. They're also worried about the so-called "organic" content that could have been pushed out, for free, on the pages run by Russian operatives.
  • Also watch for questions about what the companies are going to do to stop future attempts at foreign election interference, potentially as soon as next week's election in Virginia.

For your calendar: The companies appear before a Senate Judiciary subcommittee on Tuesday afternoon, and in front of both House and Senate Intel on Wednesday.Why it matters: It's rare for these companies to testify publicly about anything, let alone an issue as grave as foreign attempts to sway an election.

The other coast: The Russia issue is being discussed at the highest levels in the Valley's glassy corporate campuses. But it becomes a more serious issue if the bad press starts to affect how many people use the platforms — which is the core of their lucrative ad businesses.

Protester dies after car drives through closed highway in Seattle

One person is dead and another is in serious condition after a car drove onto a closed freeway in Seattle early Saturday and into protesters against police brutality, AP reports.

  • "Summer Taylor, 24, of Seattle died in the evening at Harborview Medical Center, spokesperson Susan Gregg said."

Where it stands: The suspect, Dawit Kelete of Seattle, fled the scene after hitting the protesters, and was later put in custody after another protester chased him for about a mile. He was charged with two counts of vehicular assault. Officials told the AP they did not know whether it was a targeted attack, but the driver was not impaired.

Trump's failing culture wars

Data: Google; Chart: Naema Ahmed/Axios

President Trump built his political brand by stoking the nation's culture wars, but search data is showing us how much harder it's been for him to replicate that success while running against another white man in his 70s — and while there's a coronavirus pandemic.

The big picture: Google Trends data shows Trump's "Sleepy Joe" name-calling isn't generating nearly the buzz "Crooked Hillary" (or "Little Marco") did in 2016. Base voters who relished doubting President Obama's birth certificate aren't questioning Biden's.
