It's hard to take a 9-to-5 job after you've been the president of the United States. So after leaving the White House, all former presidents receive money annually from the government.
In 2016, then-President Barack Obama vetoed a bill that would've reduced that total if a former president's outside income equals $400,000 or more.
So how much does the government pay former commanders in chief?
Former presidents also get lifetime Secret Service protection and monetary allowances for things like travel, office space and staff salaries.
Those allowances differ from person to person, but more recent former presidents tend to get more money. For example in 2015, George W. Bush's entire retirement package totaled almost $1.1 million, while Jimmy Carter's was just $430,000.
They can thank former President Harry Truman for those pensions.
After leaving the White House, Truman's finances were very modest. And partly in response to his financial situation, his successor, Dwight D. Eisenhower, signed the Former Presidents Act in 1958.
But Truman never got any money from the legislation. Eisenhower was the first to benefit from its provisions.
