FBI Investigating Election Day Robocalls Telling People To 'Stay Home'

The transcript discusses a series of robo calls made before and during the election, urging people to stay home, which experts believe may have been intended to discourage voting. These calls were widespread, affecting nearly 90% of US area codes, with over 10 million calls made in October alone. On Election Day, they were reported in several states. Unlike typical robo calls, these did not seek personal information, and the creators used advanced technology to hide their identity and location.
