Beginning in at least 2015, Donald Trump promised he would forego a salary if he became president. Shortly after the election, Donald Trump sat down for an interview with Leslie Stahl on 60 Minutes and promised he would forego his salary:

But it’s a -- I don’t even know what it is.” Stahl reminded the president-elect, “[That’s] $400,000 you’re giving up.” Again, Trump answered, “No, I’m not gonna take the salary. I’m not taking it.”

Although he says he’d never discussed it publicly, he’d been making this same claim since at least 2015. Here is a short video from his own Twitter feed where he makes the same claim:

And where does that pledge stand now? ¯\_(ツ)_/¯
