it says:

"Theodore Roosevelt (1901-1909)

President Teddy Roosevelt was pretty set in his ways when it came to breakfast. He’d have hard-boiled eggs and homemade rolls. He insisted that the eggs be cooked until solid throughout. Medium or soft-boiled eggs wouldn’t cut it. As for the rolls, they had to be fresh and there had to be a lot of them. In the rare times that he’d deviate from his routine, it was usually in favor of hominy with butter and salt."
