Question: When did the party Harlan and Stewart were affiliated with gain control of the body which determines rules of the US House and US Senate?

<P0-S0> The Standing Rules of the Senate are the parliamentary procedures adopted by the United States Senate that govern its procedure. <P0-S1> The Senate's power to establish rules derives from Article One, Section 5 of the United States Constitution: ``Each House may determine the rules of its proceedings... '' <SEP> <P1-S0> The Republicans regained the majority of the Senate in the 114th Congress, which started in January 2015; the Republicans had not controlled the Senate since January 2007. <P1-S1> They had needed a net gain of at least six seats to obtain a majority. <P1-S2> They held all of their seats, and gained nine Democratic - held seats. <P1-S3> Republicans defeated five Democratic incumbents: <SEP> <P2-S0> Whittaker was unsuited for the role and soon retired. <P2-S1> Stewart and Harlan were conservative Republicans, while Brennan was a Democrat who became a leading voice for liberalism. <P2-S2> In selecting a Chief Justice, Eisenhower looked for an experienced jurist who could appeal to liberals in the party as well as law-and-order conservatives, noting privately that Warren "represents the kind of political, economic, and social thinking that I believe we need on the Supreme Court ... <P2-S3> He has a national name for integrity, uprightness, and courage that, again, I believe we need on the Court". <P2-S4> In the next few years Warren led the Court in a series of liberal decisions that revolutionized the role of the Court. <SEP> <P3-S0> the constitution designates the vice president of the united states as president of the united states senate. <P3-S1> the constitution also calls for a president pro tempore to serve as the leader of the body when the president of the senate (the vice president) is absent. <P3-S2> in practice, neither the vice president nor the president pro tempore -- customarily the most senior (longest - serving) senator in the majority party -- actually presides over the senate on a daily basis; that task is given to junior senators of the majority party. <P3-S3> since the vice president may be of a different party than the majority and is not a member subject to discipline, the rules of procedure of the senate give the presiding officer very little power and none beyond the presiding role. <P3-S4> for these reasons, it is the majority leader who, in practice, manages the senate. <P3-S5> this is in contrast to the house of representatives where the elected speaker of the house has a great deal of discretionary power and generally presides over votes on bills. <SEP> <P4-S0> however, at the state level, the pattern of split ticket voting and divided government holds. <P4-S1> democrats currently hold one of the state's u.s. senate seats, as well as four of the five statewide offices (governor, superintendent of public instruction, secretary of state and state auditor). <P4-S2> the lone congressional district has been republican since 1996 and in 2014 steve daines won one of the state's senate seats for the gop. <P4-S3> the legislative branch had split party control between the house and senate most years between 2004 and 2010, when the mid-term elections returned both branches to republican control. <P4-S4> the state senate is, as of 2015, controlled by the republicans 29 to 21, and the state house of representatives at 59 to 41.
