I see in the future a crisis approaching that unnerves me and causes me to tremble for the safety of my country...Corporations have been enthroned and an era of corruption in high places will follow, and the money power of the country will endeavor to prolong its reign by working upon the prejudices of the people until all wealth is aggregated in a few hands and the Republic is destroyed.
—Abraham Lincoln, November 21, 1864

Well, it turns out that Lincoln didn't say that; he channeled it. According to the Illinois Historic Preservation Agency,

Allegedly written by Lincoln to Thomas Elkins on November 21, 1864. However, upon further examination by his son Robert Todd Lincoln, the source was traced to a séance in Iowa, where a medium reportedly channeled these words for the slain President.
