"The President of the United States has reposed special trust and confidence in the patriotism, valor, fidelity, and abilities of the following officers," says the order promoting Army Lieutenant Colonel Robert G. Young to the rank of full colonel.
Now, the president can't be expected to personally vet every military officer who is up for promotion, and, for all but those in the highest ranks, would obviously just rely on the recommendations of the superiors of officers on the promotions lists, but I have to wonder how the president would feel about having rubber stamped the promotion of an officer who said that blacks were better off as slaves.
