So there's this Facebook post that makes this claim:
No sitting President, in the history of The United States of America, has ever 'skipped' the funeral of a sitting US Supreme Court Justice.
Never. Until now.
Is this true?
President Eisenhower was in Colorado on October 12, 1954 and did not attend the funeral that day of Justice Robert H. Jackson, who died in office October 9, 1954. The Funeral was at Washington (Episcopal) National Cathedral.
