Hi Juan Viejo,
Eisenhower did take the oath of office as President on a Bible given to him by his mother that was printed by the Watchtower Society.
Yes, an American Standard Version which the Watchtower used at that time.
From the Watchtower of 1 June 1957 article: Conspiracy Against Jehovah’s Name?
However, in telling of President Eisenhower’s taking his oath of office and having his Bible turned to or opened at Psalm 33:12, the press did not quote that text the way it reads in that American Standard Version Bible: “Blessed is the nation whose God is Jehovah, the people whom he hath chosen for his own inheritance.” No, but the press quoted it as it reads in the King James Version: “Blessed is the nation whose God is the LORD; and the people whom he hath chosen for his own inheritance.”
