1870s, Third State of the Union Address (1871)
Context: It is a subject for regret that the reforms in this direction which were voluntarily promised by the statesmen of Spain have not been carried out in its West India colonies. The laws and regulations for the apparent abolition of slavery in Cuba and Porto Rico leave most of the laborers in bondage, with no hope of release until their lives become a burden to their employers.

Context: Free labor has the inspiration of hope; pure slavery has no hope. The power of hope upon human exertion, and happiness, is wonderful. The slave-master himself has a conception of it; and hence the system of tasks among slaves. The slave whom you can not drive with the lash to break seventy-five pounds of hemp in a day, if you will task him to break a hundred, and promise him pay for all he does over, he will break you a hundred and fifty. You have substituted hope, for the rod. And yet perhaps it does not occur to you, that to the extent of your gain in the case, you have given up the slave system, and adopted the free system of labor.

2014, Statement on Cuban policy (December 2014)
Context: While I have been prepared to take additional steps for some time, a major obstacle stood in our way –- the wrongful imprisonment, in Cuba, of a U. S. citizen and USAID sub-contractor Alan Gross for five years. Over many months, my administration has held discussions with the Cuban government about Alan’s case, and other aspects of our relationship. His Holiness Pope Francis issued a personal appeal to me, and to Cuba’s President Raul Castro, urging us to resolve Alan’s case, and to address Cuba’s interest in the release of three Cuban agents who have been jailed in the United States for over 15 years.
Today, Alan returned home –- reunited with his family at long last. Alan was released by the Cuban government on humanitarian grounds. Separately, in exchange for the three Cuban agents, Cuba today released one of the most important intelligence agents that the United States has ever had in Cuba, and who has been imprisoned for nearly two decades. This man, whose sacrifice has been known to only a few, provided America with the information that allowed us to arrest the network of Cuban agents that included the men transferred to Cuba today, as well as other spies in the United States. This man is now safely on our shores.
Having recovered these two men who sacrificed for our country, I’m now taking steps to place the interests of the people of both countries at the heart of our policy.
