Question: Who succeeds the speaker of the body which presides over any impeachment trial of the president of the country Matthias W. Day holds citizenship in as president?

<P0-S0> The proceedings unfold in the form of a trial, with each side having the right to call witnesses and perform cross-examinations. <P0-S1> Senators must also take an oath or affirmation that they will perform their duties honestly and with due diligence. <P0-S2> After hearing the charges, the Senate usually deliberates in private. <P0-S3> The Constitution requires a two thirds super majority to convict a person being impeached. <P0-S4> 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. <SEP> <P1-S0> Matthias W. Day (August 8, 1853 – September 12, 1927) was a career American army officer who received the Medal of Honor, the United States' highest military decoration, for his actions during the American Indian Wars in the latter half of the 19th century. <P1-S1> Day was a longtime officer with the African-American 9th Cavalry Regiment, seeing action during the Apache Wars against the Apache leaders Victorio and Geronimo. <SEP> <P2-S0> the speaker of the united states house of representatives presides over the lower house of congress, the house of representatives. <P2-S1> this post is second in line to the presidency -- after the vice president -- and is therefore the third highest - ranking national office overall. <P2-S2> in practice, this post is the highest - ranking in congress, because the president of the us senate is the vice president, who has his / her office, and predominant responsibilities, at the white house, and therefore does not have a day - to - day presence at the congress. <SEP> <P3-S0> this was the first impeachment of a president since creation of the office in 1789. the culmination of a lengthy political battle between johnson, a lifelong democrat and the republican majority in congress over how best to deal with the defeated southern states following the conclusion of the american civil war, the impeachment, and the subsequent trial (and acquittal) of johnson were among the most dramatic events in the political life of the nation during the reconstruction era. <P3-S1> together, they have gained a historical reputation as an act of political expedience, rather than necessity, which was based on johnson's defiance of an unconstitutional piece of legislation, and which was conducted with little regard for the will of a general public which, despite the unpopularity of johnson, opposed the impeachment. <SEP> <P4-S0> The succession follows the order of Vice President, Speaker of the House of Representatives, President pro tempore of the Senate, and then the heads of federal executive departments who form the Cabinet of the United States. <P4-S1> The United States presidential line of succession is the order in which persons may become or act as President of the United States if the incumbent President becomes incapacitated, dies, resigns, or is removed from office (by impeachment by the House of Representatives and subsequent conviction by the Senate). <P4-S2> The line of succession is set by the United States Constitution and the Presidential Succession Act of 1947 as subsequently amended to include newly created cabinet offices. <P4-S3> The Cabinet currently has fifteen members, beginning with the Secretary of State, and followed by the rest in the order of their positions' creation. <P4-S4> Those heads of department who are ineligible to act as President are also ineligible to succeed the President by succession, for example most commonly if they are not a natural - born U.S. citizen.
