From a reader:

Jonah,
In Roy Jenkins’ 2001 biography Churchill, TR invited the visiting Churchill to a dinner in Albany shortly after the then NY governor had been elected Vice-President. “There is no record of whether this dinner went badly,” Jenkins writes, “but it certainly did nothing to prevent the development of a deep and surprising Theodore Roosevelt animus against Churchill.” Jenkins also quotes from a letter that TR wrote to a British MP in 1914, in which TR states, “I have never liked Winston Churchill.” Finally Jenkins relates how, many years later, TR’s irrepressible daughter Alice was asked by Arthur Schlesinger why her father so disliked Churchill. She responded, “Because they were so alike.”
(You’ll remember TR’s most famous quote about his sassy daughter: “I can be President of the United States, or I can control Alice. I cannot possibly do both.”)
