A Washington, D.C., ban on gatherings larger than 50 people nixed Trump’s plans to spend election night at his hotel in that city. But Trump is planning an indoor event at the White House instead, with a guest list that is reported to run upwards of 400 people. This will be the highest-profile event at the White House since the Sept. 26 celebration of Amy Coney Barrett’s nomination to the Supreme Court. That gathering had … some unintended COVID-19-related side effects. Officials say everyone attending tonight will be tested for COVID-19, but testing is, at best, an unreliable method of preventing the gathering from turning into another White House superspreader event. The key problem: Individuals can be contagious before they test positive.
