Background: Daniel Milton Rooney (July 20, 1932 - April 13, 2017) was chairman of the Pittsburgh Steelers, an American football team in the National Football League (NFL), and son of the Steelers' founder, Art Rooney. Dan Rooney was elected to the Pro Football Hall of Fame in 2000 for his contributions to the game. He was credited with spearheading a requirement that NFL teams with head coach and general manager vacancies interview at least one minority candidate, which has become known as the "Rooney Rule". Rooney served as the United States Ambassador to Ireland, from July 2009 until his resignation in December 2012.
Context: On March 17, 2009, President Obama announced he had nominated Rooney to become the next US ambassador to Ireland, citing the owner's longstanding support for Irish-American charitable causes. In 2008, Rooney gave $30,000 to a Democratic Party committee that aided Obama's campaign, according to CQ MoneyLine, a non-partisan group that tracks political contributions. According to David Lewis, a Vanderbilt University political scientist and the author of The Politics of Presidential Appointments, "giving coveted ambassadorships to political supporters is a relatively low-risk way for presidents to repay campaign debts."  Secretary of State Hillary Clinton swore him in as the new ambassador to Ireland on July 1, 2009. Ambassador Rooney presented his credentials to Irish President Mary McAleese on July 3, before making his first official speaking engagement at lunch hosted by the American Chamber of Commerce Ireland.  In an interview with The Irish Times in April 2011 Rooney mentioned that he would consider resigning his ambassadorship in order to campaign for Obama's re-election. However, in a prepared statement released after that interview was published Rooney stated, "I was asked what I could do to help [Obama] in the next election and I responded that the best thing I could do would be to help him campaign. Were I to do so, it would require my resignation as ambassador to Ireland. However, I am very pleased with my accomplishments to date and I intend to continue to carry out my duties." On December 14, 2012, he resigned as US Ambassador to Ireland and returned to Pittsburgh. He would eventually be replaced in June 2014 by Kevin O'Malley.  Rooney was the maternal great-uncle of actresses Kate Mara and her sister Rooney Mara.

Problem: Background: Kenneth Lauren Burns (born July 29, 1953) is an American filmmaker, known for his style of using archival footage and photographs in documentary films. His widely known documentary series include The Civil War (1990), Baseball (1994), Jazz (2001), The War (2007), The National Parks: America's Best Idea (2009), Prohibition (2011), The Roosevelts (2014), and The Vietnam War (2017). He was also executive producer of both The West (1996, directed by Stephen Ives), and Cancer: The Emperor of All Maladies (2015, directed by Barak Goodman).
Context: Burns worked as a cinematographer for the BBC, Italian television, and others, and in 1977, having completed some documentary short films, he began work on adapting David McCullough's book The Great Bridge, about the construction of the Brooklyn Bridge. Developing a signature style of documentary filmmaking in which he "adopted the technique of cutting rapidly from one still picture to another in a fluid, linear fashion [and] then pepped up the visuals with 'first hand' narration gleaned from contemporary writings and recited by top stage and screen actors", he made the feature documentary Brooklyn Bridge (1981), which earned an Academy Award nomination for Best Documentary and ran on PBS in the United States.  Following another documentary, The Shakers: Hands to Work, Hearts to God (1984), Burns was Oscar-nominated again for The Statue of Liberty (1985). Burns frequently collaborates with author and historian Geoffrey Ward, notably on documentaries such as The Civil War, Jazz, Baseball, and the 10 part TV series The Vietnam War (aired September 2017).  Burns has gone on to a long, successful career directing and producing well-received television documentaries and documentary miniseries on subjects as diverse as arts and letters (Thomas Hart Benton, 1988); mass media (Empire of the Air: The Men Who Made Radio, 1991); sports (Baseball, 1994, updated with 10th Inning, 2010); politicians (Thomas Jefferson, 1997); music (Jazz, 2001); literature (Mark Twain, 2001); war (the 15-hour World War II documentary The War, 2007); environmentalism (The National Parks, 2009); and the Civil War (the 11-hour The Civil War, 1990, which All Media Guide says "many consider his 'chef d'oeuvre'").  According to a 2017 piece in the New Yorker, Burns and his company, Florentine Films, have selected topics for documentaries slated for release by 2030. These topics include country music, the Mayo Clinic, Muhammad Ali, Ernest Hemingway, the American Revolution, Lyndon B. Johnson, Barack Obama, Winston Churchill, the American criminal justice system, and African-American history from the Civil War to the Great Migration.
