Jabin Botsford—The Washington Post/Getty Images  by [Katie Reilly](https://time.com/author/katie-reilly/)  ## Katie Reilly Feb 14, 2017 3:57 PM UTC When [Michael Flynn resigned](http://time.com/4670208/michael-flynn-resignation-trump-white-house/?xid=homepage) as President Trump’s national security adviser on Monday night, he set a record for shortest period of time spent in the role. His 24-day tenure as Trump’s top national security aide is far shorter than that of any of his predecessors. On average, national security advisers have served for 2.6 years, [the Washington _Post_ reported](https://www.washingtonpost.com/news/morning-mix/wp/2017/02/14/flynn-sets-record-with-only-24-days-as-nsc-chief-the-average-tenure-is-about-2-6-years/?utm%5Fterm=.fe52eee11a42). Since the position was created in 1953 by President Dwight Eisenhower, 25 people have held the role, according to the _Post_. Prior to Flynn’s resignation, William H. Jackson held the record, serving for just four months in Eisenhower’s administration, the _Post_ said. Flynn resigned Monday, [admitting](http://time.com/4670178/michael-flynn-resignation-transcript-letter/?xid=homepage) that he misled Vice President Mike Pence about his conversations during the transition with the Russian ambassador to the U.S. Flynn initially told Pence that he had not discussed sanctions on Russia during the calls, but it now appears he did. Trump named retired Lt. Gen. Keith Kellogg, Jr. to serve as his acting national security adviser. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4670486/michael-flynn-resignation-record/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4670486/michael-flynn-resignation-record/"},"headline":"Michael Flynn Sets Record for Shortest National Security Adviser Tenure","datePublished":"2017-02-14T15:57:51.000Z","dateModified":"2026-02-23T03:19:19.289Z","description":"The advisers usually serve an average of 2.6 years","url":"https://time.com/4670486/michael-flynn-resignation-record/","keywords":["White House","Donald Trump","onetime"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blta3177713e49feb4f/6988ba4ea988ca47c86bb016/michael-flynn-record.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Katie Reilly","jobTitle":null,"url":"https://time.com/author/katie-reilly/"}],"articleSection":"Politics","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blta3177713e49feb4f/6988ba4ea988ca47c86bb016/michael-flynn-record.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"President Donald Trump","caption":"President Donald Trump","creditText":"Jabin Botsford—The Washington Post/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/politics/","name":"Politics"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/white-house/","name":"White House"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4670486/michael-flynn-resignation-record/","name":"Michael Flynn Sets Record for Shortest National Security Adviser Tenure"}}]}] ```
