Question: When did the party that holds the majority in the House of Representatives take control of the branch that gives regulators discretion to prohibit proprietary trades?

<P0-S0> the current minority leader nancy pelosi, of the united states house of representatives serves as floor leader of the opposition party, and is the counterpart to the majority leader. <P0-S1> unlike the majority leader, the minority leader is on the ballot for speaker of the house during the convening of the congress. <P0-S2> if the minority leader's party takes control of the house, and the party officers are all re-elected to their seats, the minority leader is usually the party's top choice for speaker for the next congress, while the minority whip is typically in line to become majority leader. <P0-S3> the minority leader usually meets with the majority leader and the speaker to discuss agreements on controversial issues. <SEP> <P1-S0> however, at the state level, the pattern of split ticket voting and divided government holds. <P1-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). <P1-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. <P1-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. <P1-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. <SEP> <P2-S0> These bills must now be reconciled. <P2-S1> 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. <P2-S2> 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. <P2-S3> The U.S. Senate passed a reform bill in May 2010, following the House which passed a bill in December 2009. <SEP> <P3-S0> They had needed a net gain of at least six seats to obtain a majority. <P3-S1> They held all of their seats, and gained nine Democratic - held seats. <P3-S2> 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. <P3-S3> Republicans defeated five Democratic incumbents: <SEP> <P4-S0> The One Hundred Fourteenth United States Congress was a meeting of the legislative branch of the United States federal government, composed of the United States Senate and the United States House of Representatives. <P4-S1> It met in Washington, D.C. from January 3, 2015, to January 3, 2017, during the final two full years of Barack Obama's presidency. <P4-S2> The 2014 elections gave the Republicans control of the Senate (and control of both houses of Congress) for the first time since the 109th Congress. <P4-S3> With 248 seats in the House of Representatives and 54 seats in the Senate, this Congress began with the largest Republican majority since the 71st Congress of 1929 -- 1931.
