text of Lincoln’s cover letter
“I transmit an authenticated copy of a joint resolution to amend the Constitution of the United States adopted by Congress and approved on the 2nd of March 1861 by James Buchanan, President.”
A copy of the amendment and it’s cover letter were sent to all state governors, including those governors of states that had seceded from the Union.
Would you send a letter notifying a governor that an amendment to strengthen slavery has passed the congress?
Would you do that? I would absolutely refuse. They can find out whatever way, but it wouldn't be through me.
