The answer is a reference to the case Marbury v. Madison resulting from a petition to the Supreme Court by William Marbury, who had been appointed Justice of the Peace in the District of Columbia by President John Adams but whose commission was not subsequently delivered. Marbury petitioned the Supreme Court to force the new Secretary of State, James Madison, to deliver the documents. The Court, with John Marshall as Chief Justice, found firstly that Madison’s refusal to deliver the commission was both illegal and correctable. The Court stopped short of ordering Madison (by writ of mandamus) to hand over Marbury’s commission, instead holding that the provision of the Judiciary Act of 1789 that enabled Marbury to bring his claim to the Supreme Court was itself unconstitutional, since it purported to extend the Court’s original jurisdiction beyond that which Article III established. The petition was therefore denied. (Wikipedia)

John Marshall (1755-1835) was nominated for Chief Justice of the Supreme Court by President John Adams. Marshall became the fourth Chief Justice on January 31, 1801. He served on the court for 34 years until his death on July 6, 1835. Marshall was Cheif Justice for the landmark cases of Marbury v. Madison and McCulloch v. Maryland.

William McKinley, the 25th President of the United States, was shot on the grounds of the Pan-American Exposition at the Temple of Music in Buffalo, New York on September 6, 1901. He was shaking hands with the public when Leon Czolgosz, an anarchist, shot him twice in the abdomen. McKinley died eight days later on September 14 of gangrene caused by the gunshot wounds.

Later that day, Theodore Roosevelt was sworn in as the 26th President at the Ansley Wilcox House in Buffalo. This made Roosevelt the youngest person (42 years, 322 days) to be inaugurated as President.

Grover Cleveland was the only person to serve two non-consecutive terms as President of the United States. Cleveland was the 22nd President from 1885 through 1889. In a very contentious campaign where tariffs were the main issue, Benjamin Harrison won by a slim margin. There were accusations of voter fraud and fixed election, particularly in Indiana. Cleveland did not challenge the result and served his full term.

Cleveland won back the Presidency in the 1892 election in what was a very calm election for the time period. Cleveland became very vocal during the Harrison administration over monetary policy including opposing the Sherman Silver Purchase Act. He was nominated by the Democrats to run again. Harrison did not campaign opting to be with his wife Caroline who was dying of tuberculosis. Following her death on October 25, 1888, two weeks prior to the election, all candidates suspended campaigning. Cleveland was the 24th President of the United States from 1893 through 1897.

Salmon P. Chase (1808 – 1873) was the sixth Chief Justice of the Supreme Court. Chase was nominated by President Abraham Lincoln while serving as the 25th Secretary of the Treasury. A significant case during his tenure was when he presided at the impeachment trial of President Andrew Johnson in 1868. With 27 states and 54 senators, it required 36 (two-thirds) guilty votes to remove Johnson from office. Johnson was acquitted with 35 guilty votes and 19 not-guilty votes. Chase served on the Supreme Court from December 6, 1864, until he died on May 7, 1873.
