2 questions:1) Is Trump currently getting paid?
Even if he was, it would hardly matter, since he has so far donated every dime of his salary to charities. One of his campaign promises was that he wouldn't accept a salary, so it seems he's trying to keep that promise.
2) How many years of government shutdown would it take to clear the deficit?
Shutdowns don't save the government any money, so this question makes no sense. The money gained by not paying personnel is immediately lost to paying those same people overtime to work through the backlogs the shutdown caused.
