Presidential facts and 'firsts'

　　In January 2017, Donald J. Trump made history when he took the oath of office as the 45th president of the United States. At 70 years old, he became the oldest elected president. Before Trump, Ronald Reagan was the oldest person to take office. He was 69 years old when he became president in 1981.

　　As the first billionaire president, Trump also replaced John F. Kennedy, the 35th president, as the richest man to serve as president.

　　Kennedy still holds the record for the youngest person to be elected president. He was 43 when he took office. Kennedy is also the youngest president to die in office. He was assassinated in 1963 in Dallas, Texas. He was 46 years old.

　　Another presidential assassination actually put the youngest person in the office of the president. In 1901, Theodore Roosevelt, then the vice president, became president at the age of 42. He took office after William McKinley, the 25th president, was shot and killed in Buffalo, New York.

　　The first president to die in office, though, was William Henry Harrison. The country’s ninth president only served 32 days, the shortest time of any president.

　　Another Roosevelt holds the record for the longest time in office. Franklin Delano Roosevelt, the 32nd president, held office for 4,422 days. After his death, the 22nd amendment was passed. It limited a person to two four-year terms as president.

　　Most Americans know that the two Roosevelts were related. But they may not know how, exactly, they were related.
