At the end of the year 2018, the President of the United States pay wages on what?

US President Donald Trump will spend his entire $ 400,000 to do charity work by the end of 2018, according to White House Press Secretary Sean Spicer.

Mr Spicer told reporters: "The President's intention is to donate his entire payroll later this year. He asked you to help choose a charity. The way we can avoid being monitored is for the press to determine where this money is needed. "
Spicer's words are a bit ironic regarding the previous "look" of the media about Trump's contribution and the management of his family's business.
While running for election, Trump has repeatedly stated that he will not receive the president's salary.
Mr. Trump is not the only US president to take this action. Earlier, former Presidents Herbert Hoover and John F. Kennedy also paid their presidency for charity.
