Abraham Lincoln actually said...
I transmit to the Senate, for consideration with a view to its ratification, an additional article to the treaty between the United States and Great Britain of the 7th of April, 1862, for the suppression of the African slave trade, which was concluded and signed at Washington on the 17th instant by the Secretary of State and Her Britannic Majesty's minister accredited to this Government.
