Question: In 2010, who controlled the senate as well as the body that presides over impeachment of the president, of the country the Liberian flag and constitution are modeled after?

<P0-S0> The One Hundred Eleventh United States Congress was a meeting of the legislative branch of the United States federal government from January 3, 2009, until January 3, 2011. <P0-S1> It began during the last two weeks of the George W. Bush administration, with the remainder spanning the first two years of Barack Obama's presidency. <P0-S2> It was composed of the Senate and the House of Representatives. <P0-S3> The apportionment of seats in the House was based on the 2000 U.S. Census. <P0-S4> In the November 4, 2008, elections, the Democratic Party increased its majorities in both chambers, giving President Obama a Democratic majority in the legislature for the first two years of his presidency. <P0-S5> A new delegate seat was created for the Northern Mariana Islands. <P0-S6> The 111th Congress had the most experienced members in history: at the start of the 111th Congress, the average member of the House had served 10.3 years, while the average Senator had served 13.4 years. <P0-S7> This Congress has been considered one of the most productive Congresses in history in terms of legislation passed since the 89th Congress, during Lyndon B. Johnson's Great Society. <SEP> <P1-S0> the senate also has a role in ratifying treaties. <P1-S1> the constitution provides that the president may only "make treaties, provided two thirds of the senators present concur" in order to benefit from the senate's advice and consent and give each state an equal vote in the process. <P1-S2> however, not all international agreements are considered treaties under us domestic law, even if they are considered treaties under international law. <P1-S3> congress has passed laws authorizing the president to conclude executive agreements without action by the senate. <P1-S4> similarly, the president may make congressional-executive agreements with the approval of a simple majority in each house of congress, rather than a two-thirds majority in the senate. <P1-S5> neither executive agreements nor congressional-executive agreements are mentioned in the constitution, leading some scholars such as laurence tribe and john yoo to suggest that they unconstitutionally circumvent the treaty-ratification process. <P1-S6> however, courts have upheld the validity of such agreements.the constitution empowers the house of representatives to impeach federal officials for "treason, bribery, or other high crimes and misdemeanors" and empowers the senate to try such impeachments. <P1-S7> if the sitting president of the united states is being tried, the chief justice of the united states presides over the trial. <P1-S8> during an impeachment trial, senators are constitutionally required to sit on oath or affirmation. <P1-S9> conviction requires a two-thirds majority of the senators present. <P1-S10> a convicted official is automatically removed from office; in addition, the senate may stipulate that the defendant be banned from holding office. <P1-S11> no further punishment is permitted during the impeachment proceedings; however, the party may face criminal penalties in a normal court of law. <SEP> <P2-S0> the presiding officer of the senate is the vice president of the united states, who is president of the senate. <P2-S1> in the vice president's absence, the president pro tempore, who is customarily the senior member of the party holding a majority of seats, presides over the senate. <P2-S2> in the early 20th century, the practice of majority and minority parties electing their floor leaders began, although they are not constitutional officers. <SEP> <P3-S0> The Republic of Liberia, beginning as a settlement of the American Colonization Society (ACS), declared its independence on July 26, 1847. <P3-S1> The United States did not recognize Liberia's independence until during the American Civil War on February 5, 1862. <P3-S2> Between January 7, 1822 and the American Civil War, more than 15,000 freed and free-born Black Americans from United States and 3,198 Afro-Caribbeans relocated to the settlement. <P3-S3> The Black American settlers carried their culture with them to Liberia. <P3-S4> The Liberian constitution and flag were modeled after the United States. <P3-S5> In January 3, 1848 Joseph Jenkins Roberts, a wealthy free-born Black American from Virginia who settled in Liberia, was elected as Liberia's first president after the people proclaimed independence. <SEP> <P4-S0> The proceedings unfold in the form of a trial, with each side having the right to call witnesses and perform cross-examinations. <P4-S1> The House members, who are given the collective title of managers during the course of the trial, present the prosecution case, and the impeached official has the right to mount a defense with his own attorneys as well. <P4-S2> Senators must also take an oath or affirmation that they will perform their duties honestly and with due diligence. <P4-S3> After hearing the charges, the Senate usually deliberates in private. <P4-S4> The Constitution requires a two thirds super majority to convict a person being impeached.
