- Leo did not attend Notre Dame [2.7], but he is, according to Sam, a lawyer [3.5]. Leo got a 1400 on his SATs [4.11].
- Leo is a veteran who flew planes during the Vietnam war [1.9] as a member of the 1044th Fighter Wing of the United States Air Force [4.1]. Or the 355th Tactical Fighter Wing [4.17]. Years later, he found out that his commanding officers gave him orders to bomb civilian targets -- a war crime [3.5]. Specifically, he flew over the DMZ [4.6] and participated in Operation Rolling Thunder, in September of 1966: Leo flew an F105 fighter out of Thailand, where he hit a target that he believed to be military [3.5].
- Leo was shot down over Hanoi; his leg was broken. His buddy Kenny O'Neil dragged Leo through the jungle and found them water during the three days they had to wait to be rescued [5.14].
- He still answers to the title "colonel" [4.8]
- He served as the Secretary of Labor six years ago [1.10].
- Leo made $40,000 a pop on the lecture circuit [1.4].
- Leo first approached Jed about running for President in November, 1997, at the State House in Concord, while Bartlet was Governor; he'd scribbled the words "Bartlet for America" on a napkin, which he gave to Jed [3.9]. Years later, Bartlet gave Leo the napkin framed, and Leo has it in his office [4.6].
- Not only did Leo convince Jed Bartlet to run [3.9], he also served as General Chairman of the campaign [3.9], assembled a killer staff [2.1], and got what the media dubbed a "dark horse candidate" elected [1.1].
- Leo has the unenviable task of breaking news of Zoey's disappearance to the President, as it's Secret Service protocol to tell the Chief of Staff first [4.22].
- He inflicts the annual Big Block of Cheese Day tradition upon his staff, complete with speech 1 [1.5].
- He offered to take a leave of absence from the White House to join Josh's legal team, were he to sue the Ku Klux Klan [2.5].
- Leo has his own cabin on Air Force One [3.1]. Bartlet originally thought that Leo's office was a closet off of the Oval Office [4.5].
- When the United States is involved in military action anywhere around the world, the Chief of Staff gets increased security [4.17].
- For being a good friend of Israel, Leo was presented with the Medal of David and a crumpled up yarmulke [4.4]
- Leo's assistant is Margaret [1.1]. She gets quite bent out of shape when he makes appointments himself [3.2] He doesn't like to lie to her, going so far as to eat half a grapefruit after he told her that's what he'd eaten for breakfast [4.1]. Apparently, Leo keeps her funnier notes in what Bartlet calls "The Margaret Museum" [4.9].
- When Jed Bartlet confesses that he's afraid he might consider giving in to the demands of Zoey's kidnappers and decides to invoke the 25th Amendment, Leo takes a series of steps to limit the scope of the Oval Office until further notice. Despite Leo's dismissal of Josh's assessment of the damage such a move could do to the President and the Democratic party as "just the political reality," Leo dramatically minimized the damage Speaker of the House Walken could do as Acting President [4.23].
- Leo edited an independent EPA report on coal mining so that it would reflect the administration's policy [5.5].
1."Jackson was showered with gifts... But his most famous gift was a gigantic cheese draped with Jackson slogans, bestowed in 1835 by the dairymen of Oswego County, New York, who had been supplying the White House with cheese since Jackson's election. At 1,400 pounds, four feet in diameter, and two feet thick, it arrived in a cart pulled by twenty-four gray horses. Jackson let it age for two years in the White House vestibule, then announced that on Washington's birthday, 1837, his last big reception before leaving office the next month, he would hold a cheese tasting. The public was invited. Shops and offices closed early, and a throng descended on the White House. The marshal of the city and his deputies screened people at the front door, but what a contemporary called 'rag-a-muffins of the city' got into the gardens, climbed to the terrace, and entered through the East Room windows to mix with congressmen, officers in dress uniform, and elaborately arrayed diplomats. The rooms overflowed with people, until the hall, the doorway, every possible space, were filled. .... The cheese was demolished in two hours; the White House floors and carpets were likewise demolished, and the mansion reeked of cheddar for months."
