This simply refers to holding ALL politicians, regardless of their position, status or political affiliation to be held to the same standards across the board. For example, you want to see the President's tax forms, fine, EVERY Congressman and Senator must produce theirs as well. You want to hold the President liable for the actions of January 6th, fine, hold all the other politicians who have called for people to resort to violence to get their points across by inciting violence in the race tempered riots over the past few years. See a few examples below. None of these politicians was impeached or reprimanded over their calls for violence.
I am not offering blind support to President Trump, however other politicians want to hold him to a different standard than they are willing to adhere to. If we are going to get back on track, we need ALL politicians to be held accountable and responsible for their actions EQUALLY!
