President-elect Donald Trump says he will only accept $1 for his salary as president.

Trump made the comments during a sit-down interview with CBS "60 Minutes," which aired in full Sunday evening. During the interview, the president-elect even admitted that he doesn't even know what the president's salary is.

"I've never commented on this, but the answer is 'no,'" Trump said when asked by host Lesley Stahl whether or not he'll accept the presidential salary.

"I think I have to by law take $1, so I'll take $1 a year," he added. "But it's a — I don't even know what it is. Do you know what the salary is?"

Stahl informed Trump that the current presidential salary is set at an annual rate of $400,000.

"No, I'm not going to take the salary. I'm not taking it," Trump reiterated.

During their interview, which focused on a wide range of topics, Stahl also asked Trump about his tax returns and whether or not he would be releasing them. The billionaire businessman said that he would, in fact, release them at "the appropriate time," but said that "nobody cares" about them — because he won the election.

"The only one who cares is, you know, you and a few people that asked that question. Obviously, the public didn't care because I won the election very easily," Trump said. "So they don't care. I never thought they did care."

If Trump were to forgo the presidential salary, he would be only the third president in history to do so. Presidents Herbert Hoover and John F. Kennedy declined to accept their presidential salaries, instead donating it to charity.
