The President shall, at stated Times, receive for his Services, a Compensation, which shall neither be increased nor diminished during the Period for which he shall have been elected, and he shall not receive within that Period any other Emolument from the United States, or any of them.
Article 2, Section 1, the US Constitution.
So why are we paying for this shit?
Give the pres 2 weeks vacation after his first year, pay all costs himself. That is what the rest of us get. No US funds for any campaign activities. Asshole buys two new million dollar + buses with government money, says they are not for campaigning, then offers as his fair way out that he will lend one them to the Repub candidate if they ask.
