Trump gives salary away to National Park Service

Less than a month after it was revealed US President Donald Trump would donate his salary, he's followed through on his promise - giving away his pay packet for his first three months in office.

Mr Trump's press secretary Sean Spicer presented a cheque for US$78,333 ($111,670) to interior secretary Ryan Zinke and Harper's Ferry park site superintendent Randy Burke, who accepted the financial boost on behalf of the National Park Service.

"The Park Service has cared for our parks since 1916 and the President's personally proud to contribute the first portion of his salary to the important mission for the Park Service, which is preserving our country's national security," Mr Spicer said.

The service manages the country's national parks and is one of a number of US government agencies to suffer significant funding cuts in Mr Trump's first budgetary proposal - though Mr Zinke did not mention that in a statement he read to the press corps.

"I'm thrilled at the President's decision to donate a cheque today. I did talk to the President last night, and he has decided, as you know, to donate his entire quarter of salary. And we're going to dedicate it and put it against the infrastructure on our nation's battlefields," he said.

Mr Spicer said in March that every cent of President Trump's salary would be donated to a good cause of the media's choosing, going as far as to admit that the move was an attempt to "avoid scrutiny" from press corps.

While he did not offer an explanation as to why that plan had been altered, Mr Spicer said that the House Counsel's Office had given the President alternatives to choose from.

Mr Trump, his daughter Ivanka and son-in-law Jared Kushner are all working in the White House for free. The trio are reportedly worth more than $1 billion combined.
