They (the Democrats) are creating a bill to compel the president to present his tax returns.
At this point we can be sure of two things.
1) The President is not like other Presidents. Yes he is a cheat(as in he cheated on his wives), most probably a crook and very definitely a liar. However, the one thing you can count on him to do is to not act like other Presidents when it comes to actually being one. This includes releasing his tax returns.
2) We will learn nothing new regarding his return(see first point). It’s not like his return will have a line item suddenly confirming anything from Russian interference to the Grassy Knoll. The only thing this does is make the Democrats look petty and vindictive, which in all fairness, many of them are.
So please find a better use of your time. It nothing else, I have some snow that’s needing shoveled, you can practice being a public servant.
