George W. Bush's tenure as the 43rd president of the United States began with his first inauguration on January 20, 2001, and ended on January 20, 2009. Bush, a Republican from Texas, took office after defeating the Democratic incumbent vice president Al Gore in the 2000 presidential election. Four years later, he won re-election in the 2004 presidential election, after defeating the Democratic nominee John Kerry. Alongside Bush's presidency, the Republican Party also held their majorities in the House of Representatives and the Senate during the 108th and 109th U.S. Congresses following the 2002 and 2004 elections, thereby attained an overall federal government trifecta. Bush was constitutionally limited to two terms and was succeeded by Democrat Barack Obama, who won the 2008 presidential election against Bush's preferred succcessor, John McCain. He is the eldest son of the 41st president, George H. W. Bush.
A decisive event reshaping Bush's administration were the terrorist attacks on September 11, 2001. In its aftermath, Congress created the Department of Homeland Security and Bush declared a global war on terrorism. He ordered an invasion of Afghanistan in an effort to overthrow the Taliban, destroy al-Qaeda, and capture Osama bin Laden. He also signed the controversial Patriot Act in order to authorize surveillance of suspected terrorists. In 2003, Bush ordered an invasion of Iraq, alleging that the Saddam Hussein regime possessed weapons of mass destruction. Intense criticism came when neither WMD stockpiles nor evidence of an operational relationship with al-Qaeda were found. Before 9/11, Bush had pushed through a $1.3 trillion tax cut program and the No Child Left Behind Act, a major education bill. He also pushed for socially conservative efforts, such as the Partial-Birth Abortion Ban Act and faith-based welfare initiatives. Also in 2003, he signed the Medicare Prescription Drug, Improvement, and Modernization Act, which created Medicare Part D.
