According to the Washington Post:
Donald Trump promised to give away his $400,000 presidential salary. And he kept that promise, publicly announcing each gift — at least, for his first 3½ years in office.
Then, in the middle of the last year, the announcements stopped.
Trump’s White House never said where — or even if — he donated the last $220,000 of his salary, covering the final six months of 2020 and the first 20 days of 2021.
Now, six months after he left office, it’s not clear where Trump donated that remaining salary — or if he donated it at all.
He also claimed he was the first US president to give away the salary, another lie alongside the other 30, 273 know false or misleading claims he made in the 4 years he occupied the presidency.
