Question: When did the political party that holds the majority in the political body that passed a bill giving regulators discretion to prohibit proprietary trades, gain control of the House?

<P0-S0> Republicans regained control of the chamber they had lost in the 2006 midterm elections, picking up a net total of 63 seats and erasing the gains Democrats made in 2006 and 2008. <P0-S1> Although the sitting U.S. President's party usually loses seats in a midterm election, the 2010 election resulted in the highest loss of a party in a House midterm election since 1938, and the largest House swing since 1948. <P0-S2> This also happened to be the Republicans' largest gain in House seats since 1938. <P0-S3> Republicans gained the most in New York state where they picked up six seats, defeating five incumbents and winning an open Democratic district. <P0-S4> The heavy Democratic Party losses were attributed to anger with President Obama, opposition to the Affordable Care Act, large budget deficits and the weak economy. <P0-S5> This was also the third consecutive midterm election in a president's first term where the Republican Party has made gains in the House of Representatives, as well as the second consecutive midterm election where party control of the said chamber changed hands. <P0-S6> Notable freshmen included future Senators Cory Gardner, Todd Young, James Lankford, and Tim Scott, future Governor of Delaware John Carney, future Director of the Office of Management and Budget Mick Mulvaney, future Secretary of State Mike Pompeo, future Lieutenant Governor of Arkansas Tim Griffin, and future Louisiana Attorney General Jeff Landry. <SEP> <P1-S0> The Senate is currently composed of 51 Republicans, 47 Democrats, and 2 independents, both of whom caucus with the Democrats. <SEP> <P2-S0> the constitution designates the vice president of the united states as president of the united states senate. <P2-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. <P2-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. <P2-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. <P2-S4> for these reasons, it is the majority leader who, in practice, manages the senate. <P2-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> <P3-S0> starting with republican nicholas longworth in 1925, and continued through the democrats' control of the house from 1931 to 1995, save for republican majorities in 1947–49 and 1953–55, all majority leaders have directly ascended to the speakership brought upon by the retirement of the incumbent. <P3-S1> the only exceptions during this period were charles a. halleck who became republican house leader and minority leader from 1959 to 1965, hale boggs who died in a plane crash, and dick gephardt who became the democrats' house leader but as minority leader since his party lost control in the 1994 midterm elections. <P3-S2> since 1995, the only majority leader to become speaker is john boehner, though indirectly as his party lost control in the 2006 midterms elections. <P3-S3> he subsequently served as republican house leader and minority leader from 2007 to 2011 and then was elected speaker when the house reconvened in 2011. in 1998, with speaker newt gingrich announcing his resignation, both majority leader dick armey and majority whip tom delay did not contest the speakership which eventually went to chief deputy whip dennis hastert. <SEP> <P4-S0> The U.S. Senate passed a reform bill in May 2010, following the House which passed a bill in December 2009. <P4-S1> These bills must now be reconciled. <P4-S2> The New York Times provided a comparative summary of the features of the two bills, which address to varying extent the principles enumerated by the Obama administration. <P4-S3> For instance, the Volcker Rule against proprietary trading is not part of the legislation, though in the Senate bill regulators have the discretion but not the obligation to prohibit these trades.
