Speaking Wednesday in Chicago as part of her book tour, Hillary Clinton let slip a bit of a historical inaccuracy.

The former secretary of state gave Abraham Lincoln credit for holding a job that the Great Emancipator never actually held: that of U.S. senator.

“I actually write about Rahm in the book,” WLS-AM reported Clinton as saying. “It was in the very first chapter, the chapter I rightly call ‘Team of Rivals’ because that’s what it was in the beginning. A senator from Illinois ran against a senator from New York just as had happened way back with a senator from Illinois named Lincoln and a senator from New York named Seward. And it turned out the same way.”

As WSL-AM pointed out, Lincoln was never elected to the U.S. Senate — he famously lost to Stephen A. Douglas after the Lincoln-Douglas debates.
