If 5 or more Republican members of Congress give statements that, by my judgment, constitute a call for Trump to resign, by the end of 2025, this will resolve YES.
Independent members of Congress caucusing with the Republicans do not count.
Senators or Representatives. Current, not former (could be in lame duck session). Any statements from before market creation do not count.
If Trump DOES resign (or announce he is going to resign), and 5+ Republican members of Congress release statements affirming / commending / supporting this decision, that will qualify to resolve this YES as well.
I will not bet in this market, so that I am able to, as objectively as possible, determine whether a statement actually constitutes a call for Trump to resign.
