input: On September 8, 2004, Rather reported on 60 Minutes Wednesday that a series of memos critical of President George W. Bush's Texas Air National Guard service record had been discovered in the personal files of Lt. Bush's former commanding officer, Lt. Col. Jerry B. Killian. Once copies of the documents were made available on the Internet, their authenticity was quickly called into question. Much of this was based on the fact that the documents were proportionally printed and displayed using other modern typographic conventions usually unavailable on military typewriters of the 1970s. The font used on the documents has characteristics that exactly match standard font features of Microsoft Word. This led to claims that the memos were forgeries. The accusations then spread over the following days into mainstream media outlets including The Washington Post, The New York Times, and the Chicago Sun-Times.  Rather and CBS initially defended the story, insisting that the documents had been authenticated by experts. CBS was contradicted by some of the experts it originally cited, and later reported that its source for the documents - former Texas Army National Guard officer Lt. Col. Bill Burkett - had misled the network about how he had obtained them.  On September 20, CBS retracted the story. Rather stated, "If I knew then what I know now, I would not have gone ahead with the story as it was aired, and I certainly would not have used the documents in question." The controversy has been referred to by some as "Memogate" and "Rathergate."  Following an investigation commissioned by CBS, CBS fired story producer Mary Mapes and asked three other producers connected with the story to resign. Many believe Rather's retirement was hastened by this incident. On September 20, 2007, Rather was interviewed on Larry King Live commenting "Nobody has proved that they were fraudulent, much less a forgery. ... The truth of this story stands up to this day."

input: Many bands have auxiliaries that add a visual component to the performance. For ceremonial bands, this could be a traditional color guard or honor guard. For drum & bugle corps and corps-style field bands, this could include Dance lines, majorettes, Auxiliary units may be collectively referred to as color guard or visual ensemble.  Auxiliaries may perform as independent groups. In the early 1970s, color guards began to hold their own competitions in the winter (after the American football season, and before the beginning of the summer drum and bugle corps season). These became known as winter guard. There are also numerous dance competitions in the off-season.  The color guard of a marching band or drum and bugle corps may contain sabers, mock rifles, and tall flags. In modern bands, other props are often used: flags of all sizes, horizontal banners, vertical banners, streamers, pom-poms, even tires, balls, and hula hoops or custom built props. The color guard may also employ stage dressing such as backdrops, portable flats, or other structures. These can be used simply as static scenery or moved to emphasize block drill, and are often used to create a "backstage" area to store equipment and hide personnel.  While military color guards were typically male, band color guards tend to be primarily female, though it is becoming more common for men to join as well. A few independent units are all-male. Guard members nearly always wear a special uniform or costume that is distinctive from that of the band, not necessarily matching in design or color. The men's and women's guard uniforms are usually designed in one of two ways: nearly identically, but with gender-specific parts (i.e. skirts) adapted for the use of the opposite sex; or complimentarily, with the two uniforms designed similarly but with variations in color or form. The color guard uniform, especially in a high school marching band, need not be in school colors; in fact, they rarely are. These uniforms are designed to represent a certain aspect of the halftime show, characterize the guard members through costumes, or tell some sort of story, and can thus be in any design or color (a surprisingly common complaint among the high school audience is that guard uniforms and equipment "aren't school colors").  Indoor color guards have become popular within high schools and universities throughout the United States. These groups perform a theme-based show in competitions after the outdoor marching band season ends. Indoor color guard shows are typically performed in school gymnasiums and are adjudicated.

input: Maulbetsch's breakthrough came on October 31, 1914, in front of 30,000 fans at Harvard. The game was one of the most anticipated matches of the year. A special train brought Michigan fans to Cambridge, Massachusetts, and hundreds of Michigan alumni from the East were on hand as "reinforcements." Though Harvard prevailed, 7-0, Maulbetsch was the big story in papers across the country. Writers from Ring Lardner to Damon Runyon told the story of Maulbetsch's performance. Lardner said: "If anyone tells you the East plays the best brand of football, Maulbetsch shot that theory full of holes." According to Runyon, the Wolverines used "the mighty Maulbetsch as their battering ram", and he "gained enough ground against Harvard to bury a German army corps." Football writer Frank G. Menke said: "No westerner ever created half the stir in the east as did this Michigander . . . His peculiar, baffling style of attack, backed by phenomenal strength almost always earned for him gains of 5 to 20 yards every time he was called upon to carry the ball." Another writer noted Maulbetsch's skill as a "line breaker" as he "carried the ball repeatedly through the Harvard line and into the secondary defense with bullet-like rushes that upset tackler after tackler." Maulbetsch was responsible for four-fifths of Michigan's ground gains, and on several occasions his dives reportedly "had so much power that he dove right through a double line of crimson players and went sprawling on the ground twelve to twenty feet clear of the double line."  While every report indicates that Maulbetsch had a big day, the accounts vary dramatically as to exactly how many yards he gained. Frank Menke reported after the game that Maulbetsch gained 300 yards. A 1938 newspaper account said he "gained 350 yards from scrimmage." Yet, his 1951 obituary indicated he gained 133 yards in 30 attempts.  Despite Maulbetsch's efforts, Michigan was never able to punch the ball across the goal line. Many blamed Michigan's quarterback who switched to another back every time after Maulbetsch "took the ball to the shadow of the Crimson goal posts." In answer to the question why Michigan was unable to score, Frank Menke said: "Ask the fellow who quarterbacked for Michigan that day. His actions were too mystifying for the spectators to figure out."  When Harvard reneged on an agreement to play a game in Ann Arbor in 1915, sports writers concluded it was to avoid facing Maulbetsch again. Said one reporter: "When faih Hahvahd [sic] saw what Maulbetsch did in the first clash, it decided it cared to see no more of him. He was too rough."
