A campaign hat (also campaign cover, drill instructor cover, drill sergeant hat, lemon squeezer, Montana Peak, ranger hat, sergeant hat, Scouts hat and Smokey Bear') is a broad-brimmed felt or straw hat, with a high crown, pinched symmetrically at the four corners (the "Montana crease").

It is associated with the New Zealand Army, the Royal Canadian Mounted Police, the World War I ground forces of the United States Army, contemporary U.S. military drill sergeants, state police forces, park rangers (and from them, their logo-cartoon and mascot Smokey Bear), Boy Scouts, and others.

Although the campaign hat is occasionally referred to as a Stetson, this is from its common manufacture in the late 19th century by that company. It should not be confused with the quite different Stetson hat type with a different brim and crease, commonly known as the cowboy hat, and which is more commonly meant by the term "Stetson" today. The campaign hat also should not be confused with a slouch hat.

The origins of the hat can be traced to the 1840s when army troops posted in the west took to wearing civilian hats which were far more practical than the shakos or kepis then in vogue with most western armies. The name started to be used after the 1872–1876 regulations which introduced a black felt hat — which could be drab after 1883 — for fatigue use derived from the types popularized during the American Civil War.

Donald John Trump, Sr. (born June 14, 1946) is an American business magnate, television personality and author. He is the chairman and president of The Trump Organization and the founder of Trump Entertainment Resorts. Trump's extravagant lifestyle, outspoken manner and role on the NBC reality show The Apprentice have made him a well-known celebrity who was No. 17 on the 2011 Forbes Celebrity 100 list. He is well-known as a real-estate developer who amassed vast hotel, casino, and other real-estate properties, in the New York City area and around the world.

Trump is the son of Fred Trump, a wealthy New York City real-estate developer. He worked for his father's firm, Elizabeth Trump & Son, while attending the Wharton School of the University of Pennsylvania, and in 1968 officially joined the company. He was given control of the company in 1971 and renamed it The Trump Organization.

In 2010, Trump expressed an interest in becoming a candidate for President of the United States in the 2012 election. In May 2011, he announced he would not be a candidate, but a few weeks later he said he had not completely ruled out the possibility. In December 2011, Trump was suggested as a possible Vice Presidential selection by Michele Bachmann. Bachmann has since suspended her presidential campaign.
