The Republican National Committee on Sunday tweeted a quote wrongly attributed to Abraham Lincoln in a post celebrating the former president's birthday.

"His leadership brought us together; his legacy inspires us still. Happy Birthday, President Lincoln!" the tweet on the GOP read.

The tweet included an image with the quote: "And in the end, it's not the years in your life that count. It's the life in your years."
According to Quote Investigator, there is no "substantive evidence that Lincoln used the expression."

The website said it found the earliest use of the adage in an advertisement for a 1947 book by Edward J. Stieglitz.
 
Stieglitz was credited with using the phrase in a 1949 column in the Hartford Courant newspaper.
 
The site said it would "tentatively credit" Stieglitz with the use of the saying.

"However, it is possible that the statement was crafted by an advertising copywriter instead of Stieglitz himself. It is also possible that earlier instances exist that QI has not yet located," the site said.

"Adlai Stevenson did use the saying on more than one occasion while giving speeches. The attachment to Lincoln is currently unsupported."
