Interesting find! I don’t know if that’s a photo of the man we know as Jack Smith or if Jack Smith just happens to look like another man named Avi Hauermann. I do know that President Trump isn’t known for making odd statements that aren’t true - quite the opposite, in fact. If President Trump hinted that Jack Smith isn’t his real name, we can probably bet the farm that it isn’t.
His actual name is John Luman Smith. Not sure that helps you any.
