It's crazier than that:

"According to a Congressional review, Congress reconvened at 8pm on January 6. It's likely that staff computer use began mere minutes after Congress reconvened. Obviously, there was no way to completely lift and replace thousands of machines instantly. Therefore, from that moment until now, members and their staff have been using digital devices that may have been compromised. That means that all communications, files, and network connections from and to those devices may have also been compromised."
