Document 2: Impeachment in the United States: Impeachment in the United States is the process by which the lower house of a legislature brings charges against a civil officer of government for crimes alleged to have been committed, analogous to the bringing of an indictment by a grand jury. At the federal level, this is done by the House of Representatives. Most impeachments have concerned alleged crimes committed while in office, though there have been a few cases in which officials have been impeached and subsequently convicted for prior crimes. The impeached official remains in office until a trial is held. That trial, and their removal from office if convicted, is separate from the act of impeachment itself. Analogous to a trial before a judge and jury, these proceedings are (where the legislature is bicameral) conducted by upper house of the legislature, which at the federal level is the Senate.
Document 3: Impeachment in the United States: Impeachment in the United States is an enumerated power of the legislature that allows formal charges to be brought against a civil officer of government for crimes alleged to have been committed. Most impeachments have concerned alleged crimes committed while in office, though there have been a few cases in which Congress has impeached and convicted officials partly for prior crimes. The actual trial on such charges, and subsequent removal of an official upon conviction, is separate from the act of impeachment itself. Impeachment proceedings have been initiated against several presidents of the United States. Andrew Johnson and Bill Clinton are the only two presidents to have been successfully impeached by the House of Representatives, and both were later acquitted by the Senate. The impeachment process against Richard Nixon was never completed, as Nixon resigned his office before the vote of the full House for impeachment, but such a vote was widely expected to pass, and the threat of it and a subsequent conviction in the Senate was the impetus for Nixon's departure. To date, no president has been removed from office by impeachment and conviction. The impeached official continues in office until conviction.
Document 4: John Kerry: In January 2014, having met with Secretary of State, Archbishop Pietro Parolin, Kerry said "We touched on just about every major issue that we are both working on, that are issues of concern to all of us. First of all, we talked at great length about Syria, and I was particularly appreciative for the Archbishop’s raising this issue, and equally grateful for the Holy Father’s comments – the Pope's comments yesterday regarding his support for the Geneva II process. We welcome that support. It is very important to have broad support, and I know that the Pope is particularly concerned about the massive numbers of displaced human beings and the violence that has taken over 130,000 lives".
Document 5: Ayesha Gaddafi: In 2010 after sanctions were imposed on Iraq, she arrived in Baghdad with a delegation of 69 officials. Shortly before the invasion of Iraq in 2003, she met with Saddam Hussein. In 2011, she strongly denounced the policies of U.S. Secretary of State Hillary Clinton and U.S. President Barack Obama, calling for a mediation of the Libyan Civil War through an international organization which would exclude them.Ayesha has served as a mediator on behalf of the government with European Union corporations.
Document 6: Impeachment in the United States: At the federal level, Article I, Section 2, Clause 5 of the Constitution grants to the House of Representatives ``the sole power of impeachment '', and Article I, Section 3, Clause 6 grants to the Senate`` the sole Power to try all Impeachments''. In considering articles of impeachment, the House is obligated to base any charges on the constitutional standards specified in Article II, Section 4: ``The President, Vice President, and all civil Officers of the United States shall be removed from Office on Impeachment for, and conviction of, Treason, Bribery, or other High Crimes and Misdemeanors ''. (Full text of clauses)
Document 7: Myanmar: The impact of the post-election reforms has been observed in numerous areas, including ASEAN's approval of Myanmar's bid for the position of ASEAN chair in 2014; the visit by United States Secretary of State Hillary Clinton in December 2011 for the encouragement of further progress—it was the first visit by a Secretary of State in more than fifty years (Clinton met with the Burmese president and former military commander Thein Sein, as well as opposition leader Aung San Suu Kyi); and the participation of Aung San Suu Kyi's National League for Democracy (NLD) party in the 2012 by-elections, facilitated by the government's abolition of the laws that previously barred the NLD. As of July 2013, about 100 political prisoners remain imprisoned, while conflict between the Burmese Army and local insurgent groups continues.

Document 9: John Kerry: Kerry and his second wife, Mozambican-born businesswoman and philanthropist Maria Teresa Thierstein Simões Ferreira (known as Teresa), the widow of Kerry's late Pennsylvania Republican Senate colleague Henry John Heinz III, were introduced to each other by Heinz at an Earth Day rally in 1990. Early the following year, Senator Heinz was killed in a plane crash near Lower Merion. Teresa has three sons from her previous marriage to Heinz, Henry John Heinz IV, André Thierstein Heinz, and Christopher Drake Heinz. Heinz and Kerry were married on May 26, 1995, in Nantucket, Massachusetts.
Document 10: Impeachment: Similar to the British system, Article One of the United States Constitution gives the House of Representatives the sole power of impeachment and the Senate the sole power to try impeachments of officers of the U.S. national government. (Various state constitutions include similar measures, allowing the state legislature to impeach the governor or other officials of the state government.) In contrast to the British system, in the United States impeachment is only the first of two stages, and conviction during the second stage requires a two - thirds majority vote. Impeachment does not necessarily result in removal from office; it is only a legal statement of charges, parallel to an indictment in criminal law. An official who is impeached faces a second legislative vote (whether by the same body or another), which determines conviction, or failure to convict, on the charges embodied by the impeachment. Most constitutions require a supermajority to convict. Although the subject of the charge is criminal action, it does not constitute a criminal trial; the only question under consideration is the removal of the individual from office, and the possibility of a subsequent vote preventing the removed official from ever again holding political office in the jurisdiction where he or she was removed. Impeachment with respect to political office should not be confused with witness impeachment.
Document 11: Impeachment of Bill Clinton: Leading to the impeachment, Independent Counsel Ken Starr turned over documentation to the House Judiciary Committee. Chief Prosecutor David Schippers and his team reviewed the material and determined there was sufficient evidence to impeach the president. As a result, four charges were considered by the full House of Representatives; two passed, making Clinton the second president to be impeached, after Andrew Johnson in 1868, and only the third against whom articles of impeachment had been brought before the full House for consideration (Richard Nixon resigned from the presidency in 1974, while an impeachment process against him was underway).
Document 12: United States Senate: The House of Representatives has impeached sixteen officials, of whom seven were convicted. (One resigned before the Senate could complete the trial.) Only two presidents of the United States have ever been impeached: Andrew Johnson in 1868 and Bill Clinton in 1998. Both trials ended in acquittal; in Johnson's case, the Senate fell one vote short of the two-thirds majority required for conviction.
Document 13: Impeachment in the United States: At the federal level, Article Two of the United States Constitution states in Section 4 that ``The President, Vice President, and all civil Officers of the United States shall be removed from Office on Impeachment for, and conviction of, Treason, Bribery, or other High Crimes and Misdemeanors. ''The House of Representatives has the sole power of impeaching, while the United States Senate has the sole power to try all impeachments. The removal of impeached officials is automatic upon conviction in the Senate. In Nixon v. United States (1993), the Supreme Court determined that the federal judiciary can not review such proceedings.
Document 14: John Kerry: On December 15, 2012, several news outlets reported that President Barack Obama would nominate Kerry to succeed Hillary Clinton as Secretary of State, after Susan Rice, widely seen as Obama's preferred choice, withdrew her name from consideration citing a politicized confirmation process following criticism of her response to the 2012 Benghazi attack. On December 21, Obama proposed the nomination which received positive commentary. His confirmation hearing took place on January 24, 2013, before the Senate Foreign Relations Committee, the same panel where he first testified in 1971. The committee unanimously voted to approve him on January 29, 2013, and the same day the full Senate confirmed him on a vote of 94–3. In a letter to Massachusetts Governor Deval Patrick, Kerry announced his resignation from the Senate effective February 1.
