Did Paul Ryan have to show his tax returns to Romney?

Letter to the Editor

Usually the Vice Presidential vetting process is pretty thorough. Romney had to collect a lot of information about the people he was considering choosing for his running mate. Which makes me wonder, did Paul Ryan turn over his tax returns to Romney? If so – is the voting public going to get to see them too? After all, the two of them are applying to us to choose them as our leaders. They are running on tax reform issues. Shouldn’t they show us what taxes they pay like Obama and Biden did?
