Deeper sigh .... maybe because the President hasn't chosen where his salary will be donated. You know ... busy running the country and everything.
Besides, truly rich people don't focus on a monthly paycheck. Ever. ^-^
It's hard to keep track of everything that has been said but from what I researched this is what I remember and found while searching news articles and video to refresh my memory.
During the campaign Trump said he was not going to take a salary at all. Then it was determined that legally, the POTUS had to accept a salary. Or at least that was the interpretation. Back in March when the same question arose about this same thing. Sean Spicer said that the POTUS hadn't decided yet where the money was to go and would donate at the "end of the year". He also said the media was going to choose the charity.
Sarah Huckabee Sanders told the press it was going to be donated back to the US Treasury.
Then on April 3 of this year Spicer said in a press conference that the President was going to donate his first quarter salary to the National Park Service. The Interior Secretary actually accepted the check at the podium and said it was to be used to support the infrastructure on our country's battlefields.
Trump is no longer just the average rich guy. He has made promises repeatedly and the expectation is that as POTUS it is a priority of his to keep those promises. It also seems to me that with all of the different statements made by his administration that Trump has thought about his monthly salary a lot. When pressed about it at least.
Trump also promised to donate any profits made from his hotels and other businesses back to the Treasury Dept. As of March of this year no accounting has been made or plan submitted from the law firm that made the announcement in Trump's behalf.
