This is ridiculous. Anything which needed to be debated should have already been argued in a federal court. Over the course of the last 6 weeks the Trump legal representation has had multiple opportunities to make their case for voter fraud in the 2020 Presidential election. In one case, they stood before a Trump-appointed Judge, Stephanos Bibas, and didn't even argue that fraud had occurred in Pennsylvania... despite insisting that it had while giving interviews on Fox News.
Trying to overturn the results of a Presidential election by way of Congress, instead of through our courts, is not Constitutional. It also sets a bad precedent for future elections. Republicans will not like it when a Democratic Party nominee follows Trump's blue print for how to behave like a spoiled brat after losing a Presidential election... and if American politics has taught us anything, it's that what goes around comes around.
