NEW: False Claims that Biden ‘Lost’ Pennsylvania Surge, and Tech Companies Struggle to Keep Up

This is one of the starkest and clearest misinformation paths I've seen lately. And I can't stress this enough, this path is VERY well-known among misinformation reporters & researchers.

It started with tweets from folks like Pam Bondi & Rudy Giuliani that Real Clear Politics had "rescinded" its call that PA went to Biden. That was picked up and repeated verbally in a YouTube video. Then the YouTube video was shared in private FB groups

The YouTube video! Is on a verified account! Running ADS! And it gained nearly 900,000 views in just 12 hours, largely because of shares on Facebook. YT says this doesn't violate its rules 🤯 https://t.co/04METfLeOq

MEANWHILE ON FACEBOOK—a CrowdTangle search shows most of this activity is in PRIVATE FB groups, beyond what researchers and journalists can see.

Only 2.5 percent of FB activity—likes, shares, comments—is visible on public FB. I truly am *losing my mind* https://t.co/04METfLeOq
