That is good ammo if that letter was notarized through a person who has authority to administer an oath, not then Trump's lawyers dropped the ball again. Most of the words in that letter will be parsed to hades and back.
I think it is general knowledge, don’t think the ball was dropped or anything. I believe it is simply regarded by the corrupt judge as not germane, and that is that.
Maybe someone else here can explain the deal with it.
