US President Bill Clinton awards former President Theodore Roosevelt a posthumous Medal of Honor for his service in the Spanish-American War.

Theodore Roosevelt Jr. ( ROH-z-velt; October 27, 1858 January 6, 1919), often referred to as Teddy or his initials T. R., was an American politician, statesman, conservationist, naturalist, historian, and writer who served as the 26th president of the United States from 1901 to 1909. He previously served as the 25th vice president under William McKinley from March to September 1901, and as the 33rd governor of New York from 1899 to 1900. Having assumed the presidency after McKinley's assassination, Roosevelt emerged as a leader of the Republican Party and became a driving force for anti-trust and Progressive policies.

Roosevelt was a sickly child with debilitating asthma but partly overcame his health problems by embracing a strenuous lifestyle. He integrated his exuberant personality, a vast range of interests and achievements into a "cowboy" persona defined by robust masculinity. He was home-schooled and began a lifelong naturalist avocation before attending Harvard. His book The Naval War of 1812 (1882) established his reputation as a learned historian and popular writer. Upon entering politics, he became the leader of the reform faction of Republicans in New York's state legislature. His wife and mother both died in the same night and he was psychologically devastated. He recuperated by buying and operating a cattle ranch in the Dakotas. He served as Assistant Secretary of the Navy under President William McKinley and in 1898 helped plan the highly successful naval war against Spain. He resigned to help form and lead the Rough Riders, a unit that fought the Spanish army in Cuba to great publicity. Returning a war hero, he was elected governor of New York in 1898. The New York state party leadership disliked his ambitious agenda and convinced McKinley to make Roosevelt his running mate in the 1900 election. Roosevelt campaigned vigorously, and the McKinleyRoosevelt ticket won a landslide victory based on a platform of victory, peace and prosperity.

Roosevelt assumed the presidency at age 42 after McKinley was assassinated in September 1901. He remains the youngest person to become president of the United States. Roosevelt was a leader of the progressive movement and championed his "Square Deal" domestic policies, promising the average citizen fairness, breaking of trusts, regulation of railroads, and pure food and drugs. He prioritized conservation and established national parks, forests, and monuments intended to preserve the nation's natural resources. In foreign policy, he focused on Central America where he began construction of the Panama Canal. He expanded the Navy and sent the Great White Fleet on a world tour to project American naval power. His successful efforts to broker the end of the Russo-Japanese War won him the 1906 Nobel Peace Prize. Roosevelt was elected to a full term in 1904 and continued to promote progressive policies. He groomed his close friend William Howard Taft to succeed him in the 1908 presidential election.

Roosevelt grew frustrated with Taft's brand of conservatism and belatedly tried to win the 1912 Republican nomination for president. He failed, walked out, and founded the Progressive Party. He ran in the 1912 presidential election and the split allowed the Democratic nominee Woodrow Wilson to win the election. Following the defeat, Roosevelt led a two-year expedition to the Amazon basin where he nearly died of tropical disease. During World War I, he criticized Wilson for keeping the country out of the war; his offer to lead volunteers to France was rejected. He considered running for president again in 1920, but his health continued to deteriorate. He died in 1919. He is generally ranked in polls of historians and political scientists as one of the greatest presidents in American history.

William Jefferson Clinton (né Blythe III; born August 19, 1946) is an American politician who served as the 42nd president of the United States from 1993 to 2001. He previously served as governor of Arkansas from 1979 to 1981 and again from 1983 to 1992, and as attorney general of Arkansas from 1977 to 1979. A member of the Democratic Party, Clinton became known as a New Democrat, as many of his policies reflected a centrist "Third Way" political philosophy. He is the husband of Hillary Clinton, who was a senator from New York from 2001 to 2009, secretary of state from 2009 to 2013 and the Democratic nominee for president in the 2016 presidential election.

Clinton was born and raised in Arkansas and attended Georgetown University. He received a Rhodes Scholarship to study at University College, Oxford, and he later graduated from Yale Law School. He met Hillary Rodham at Yale; they married in 1975. After graduating from law school, Clinton returned to Arkansas and won election as state attorney general, followed by two non-consecutive terms as Arkansas governor. As governor, he overhauled the state's education system and served as chairman of the National Governors Association. Clinton was elected president in the 1992 presidential election, defeating incumbent Republican president George H. W. Bush and independent businessman Ross Perot. At 46 years old, he became the third-youngest president of the United States.

Clinton presided over the longest period of peacetime economic expansion in American history. He signed into law the North American Free Trade Agreement (NAFTA) and the Violent Crime Control and Law Enforcement Act, but failed to pass his plan for national health care reform. In the 1994 elections, the Republican Party won unified control of Congress for the first time in 40 years, however, Clinton was reelected in the 1996 with a landslide victory. Starting in the mid 1990s, he began an ideological evolution as he became much more conservative in his domestic policy advocating for welfare reform and the State Children's Health Insurance Program, as well as financial deregulation measures. He also appointed Ruth Bader Ginsburg and Stephen Breyer to the U.S. Supreme Court. During the last three years of Clinton's presidency, the Congressional Budget Office reported a budget surplus—the first such surplus since 1969. In foreign policy, Clinton ordered U.S. military intervention in the Bosnian and Kosovo wars, signed the Dayton Peace agreement. He also called for the expansion of NATO in Eastern Europe and many former Warsaw Pact members joined NATO during his presidency. Clinton's foreign policy in the Middle East saw him sign the Iraq Liberation Act which gave aid to groups against Saddam Hussein. He also participated in the Oslo I Accord and Camp David Summit to advance the Israeli–Palestinian peace process, and assisted the Northern Ireland peace process.

Clinton's second term would be dominated by the Monica Lewinsky scandal which began in 1996, when he began a sexual affair with 22-year-old White House intern Monica Lewinsky. In January 1998, news of the sexual relationship made tabloid headlines. The scandal escalated throughout the year, culminating on December 19 when Clinton was impeached by the House of Representatives, becoming the second U.S. president to be impeached after Andrew Johnson. The two impeachment articles that the House passed were centered around Clinton using the powers of the presidency to obstruct the investigation and that he lied under oath. In 1999 Clinton's impeachment trial begin in the Senate. Clinton was acquitted on both charges as the Senate failed to cast 67 votes against him, the conviction threshold.

Clinton left office in 2001 with the highest end-of-term approval rating of any U.S. president since Franklin D. Roosevelt. His presidency has been ranked among the upper tier in historical rankings of U.S. presidents. However, his personal conduct and allegations of sexual assault against him have made him the subject of substantial scrutiny. Since leaving office, he has been involved in public speaking and humanitarian work. He created the Clinton Foundation to address international causes such as the prevention of HIV/AIDS and global warming. In 2009, he was named the United Nations Special Envoy to Haiti. After the 2010 Haiti earthquake, Clinton and George W. Bush formed the Clinton Bush Haiti Fund. He has remained active in Democratic Party politics, campaigning for his wife's 2008 and 2016 presidential campaigns.
