"It is a great honor to pay tribute to Jose Marti, who gave his life for independence of his homeland. His passion for liberty, freedom, and self-determination lives on in the Cuban people today," Obama wrote in dark ink in the book after he laid a wreath and toured the memorial dedicated to the memory of Jose Marti.
