It's true that it wouldn't have been reported the way it was.
However, that doesn't mean someone wouldn't have done their homework to find out how the expenses had been recorded. That is how we can keep track of personal expenses such as vacations and golfing, employee expenditures paid for by the government compared to regular government operating expenses.
Were the personal expenditures justified or outside the norm? Does someone need to be reined in on their personal expenditures paid for by the taxpayer?
imo, Trump sending Pence on this political mission was a waste of taxpayer's money. It was not necessary nor did it add anything to what Trump had already made clear in his Twitter messages and publicly in his campaign support speeches that were broadcasted and written about in the media.
There is nothing business like about this waste.
