Here's a journalist reporting that Trump's positive COVID-19 test will "stop all business" in the U.S. Senate due to a recent meeting with Mitch McConnell and "other senators" over his SCOTUS nominee, stating that "all must quarantine" as a result of Trump's positive COVID-19 test:
This stops all business in Congress, as Trump and Amy Coney Barrett were with McConnell, met with other senators.
All must quarantine. No business can go on.
The nomination to SCOTUS must wait until after the election.
