I'm pretty sure the law says we have to pay the President.
The President shall receive in full for his services during the term for which he shall have been elected compensation in the aggregate amount of $400,000 a year, to be paid monthly, and in addition an expense allowance of $50,000 to assist in defraying expenses relating to or resulting from the discharge of his official duties. Any unused amount of such expense allowance shall revert to the Treasury pursuant to
section 1552 of title 31, United States Code. No amount of such expense allowance shall be included in the gross income of the President. He shall be entitled also to the use of the furniture and other effects belonging to the United States and kept in the Executive Residence at the White House.
Now what he does with it is his business.
Monday Spicer said: "the president's intention right now is to donate his salary at the end of the year."

I guess you all will have to wait until the end of the year to get all butt hurt about it.
