111th United States Congress

The 111th United States Congress was a meeting of the legislative branch of the United States federal government from January 3, 2009, until January 3, 2011. It began during the last weeks of the George W. Bush administration, with the remainder spanning the first two years of Barack Obama's presidency. It was composed of the Senate and the House of Representatives. The apportionment of seats in the House was based on the 2000 U.S. census.

In the November 2008 elections, the Democratic Party increased its majorities in both chambers (including – when factoring in the two Democratic caucusing independents – a brief filibuster-proof 60-40 supermajority in the Senate), and with Barack Obama being sworn in as president on January 20, 2009, this gave Democrats an overall federal government trifecta for the first time since the 103rd Congress in 1993.

However, the Senate supermajority only lasted for a period of 72 working days while the Senate was actually in session. A new delegate seat was created for the Northern Mariana Islands. The 111th Congress had the most long-serving 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. The Democratic Party would not simultaneously control both the U.S. House of Representatives and the U.S. Senate again until more than a decade later, during the 117th Congress.

The 111th Congress was the most productive congress since the 89th Congress. It enacted numerous significant pieces of legislation, including the Lilly Ledbetter Fair Pay Act, the American Recovery and Reinvestment Act, the Patient Protection and Affordable Care Act, the Dodd–Frank Wall Street Reform and Consumer Protection Act, and the New START treaty.

Major events

 * January 2009: Two Senate seats were disputed when the Congress convened:
 * An appointment dispute over the Illinois seat vacated by President Barack Obama arose following Illinois Governor Rod Blagojevich's solicitation of bribes in exchange for an appointment to the Senate. Roland Burris (D) was appointed to the seat on December 31, 2008, but his credentials were not accepted until January 12, 2009.
 * An election dispute over the Minnesota seat previously held by Norm Coleman (R), between Coleman and challenger Al Franken (D), was decided on June 30, 2009, in favor of Franken. Franken's admission briefly gave the Senate Democratic caucus 60 votes, enough to defeat a filibuster in a party-line vote.
 * January 8, 2009: Joint session counted the Electoral College votes of the 2008 presidential election.
 * January 20, 2009: Barack Obama became 44th President of the United States.
 * February 24, 2009: President Obama addressed a joint session of Congress
 * April 28, 2009: Senator Arlen Specter switched from the Republican Party to the Democratic Party.
 * September 9, 2009: President Obama addressed a joint session of Congress to promote health care reform, which Representative Joe Wilson (R) interrupted by shouting at the President.
 * January 21, 2010: Citizens United v. FEC: The U.S. Supreme Court struck down limits on campaign contributions by nonprofits, corporations, labor unions and other associations.
 * January 25, 2010: 2010 State of the Union Address
 * February 4, 2010: Republican Scott Brown's election to the Senate ended the Democratic super-majority.
 * April 20 – September 19, 2010: Deepwater Horizon oil spill
 * November 2, 2010: 2010 general elections, in which Republicans regained control of the House while the Democrats remained in control of the Senate.
