Context: Howard Morgan Griffith (born March 15, 1958) is an American politician who has been the U.S. Representative for Virginia's 9th congressional district since 2011.  He is a member of the Republican Party and the Freedom Caucus.  The district takes in a large swath of southwestern Virginia, including the New River Valley. The Second Amendment Caucus, also known as the House Second Amendment Caucus, is a congressional caucus consisting of conservative and libertarian Republican members of the United States House of Representatives who support Second Amendment rights.  It was formed in 2016 to "promote a pro-gun agenda" according to founding chairman Thomas Massie. The House Liberty Caucus is a congressional caucus consisting of conservative, libertarian, and libertarian conservative Republican members of the United States House of Representatives.  It hosts a bimonthly luncheon in Washington, D.C. The group was founded by Rep. Justin Amash of Michigan and joined by Republican members who wanted to "focus on specific issues like economic freedom, individual liberty, and following the Constitution".  The caucus has also been characterized as "conservative with a libertarian emphasis" and associated with the Tea Party movement. The Tea Party Caucus (TPC) is a congressional caucus of conservative members of the Republican Party in the United States House of Representatives.  The Caucus was founded in July 2010 by Minnesota Congresswoman Michele Bachmann who was its first chair.  From July 2012 to April 2013 the Tea Party Caucus neither met nor posted news on its webpage, leading observers to describe it as "dead," "inactive," and "defunct."  In April 2013, Mick Mulvaney of South Carolina filed paperwork to create a new Tea Party Caucus, but found that Bachmann intended to continue the caucus, starting with an event on April 25, 2013.  On June 19, 2014, Tea Party Caucus member Steve Scalise of Louisiana was elected as the House Majority Whip.  The Caucus was reconstituted in the 114th Congress in January 2015.  Rep. Tim Huelskamp of Kansas became the chair in February 2015.  Huelskamp lost party primary election in 2016.  The Caucus is now largely inactive.  Though the primary functions of the Caucus have varied from year to year, its members have promoted budget cuts, including significant cuts in non-defense spending and adherence to the movement's interpretation of the Constitution.  The caucus's members have also advocated socially conservative legislation, supported the right to keep and bear arms, and promoted limited government. A congressional caucus is a group of members of the United States Congress that meets to pursue common legislative objectives.  Formally, caucuses are formed as congressional member organizations (CMOs) through the United States House of Representatives and the United States Senate and governed under the rules of these chambers.  In addition to the term caucus, they are sometimes called conferences (especially Republican ones), coalitions, study groups, task forces, or working groups.  Many other countries use the term "parliamentary group"; for example, the UK Parliament has many all-party parliamentary groups. The Freedom Caucus, also known as the House Freedom Caucus, is a congressional caucus consisting of conservative and libertarian Republican members of the United States House of Representatives.  It was formed in 2015 by what member Jim Jordan called a "smaller, more cohesive, more agile and more active" group of conservative Congressmen. The Tuesday Group is an informal caucus of approximately 50 moderate Republican members of the United States House of Representatives in the 114th Congress (2015–2017).  It was founded in 1994 in the wake of the Republican takeover of the House.  The Republican House caucus was dominated by conservative Republicans and the Tuesday Group was founded to counterbalance that conservative trend.  There were approximately 40 members when it was founded.  In 2007 the Tuesday Group founded its own political action committee. On March 8, 2011, the United States House of Representatives created the 'Wounded to Work' Congressional Caucus' under the leadership of Congressmen Mike Conaway (R-TX), Robert Andrews (D-NJ), Scott Rigell (R-VA) and Congresswoman Madeleine Z. Bordallo (D-GM).  The Wounded to Work Caucus is the first Congressional Caucus to deal with the needs of active duty military personnel who have been wounded in the service of their nation.  The Caucus and its volunteers will be promoting employment, through Congressional internships or shadowing, as appropriate, and the education and training of military personnel.  The final goal is to provide support for the creation and development of education and training programs within the private sector in order to expand the employability of participating military personnel. The Congressional Caucus for Women's Issues is a bipartisan membership organization within the House of Representatives committed to advancing women's interests in Congress.  It was founded by fifteen Congresswomen on April 19, 1977, and was originally known as the Congresswomen’s Caucus.  Its founding co-chairs were Reps. Elizabeth Holtzman, a New York Democrat, and Margaret Heckler, a Massachusetts Republican.  In 1981, men were invited to join and the name of the organization was therefore changed to the Congressional Caucus for Women’s Issues.  However, in January 1995, the U.S. House of Representatives voted to eliminate funding for offices and staff of caucus organizations on Capitol Hill; therefore, the Congresswomen reorganized themselves into a Members’ organization.  It is still called the Congressional Caucus for Women’s Issues, but men no longer belong to it.  Today its membership consists of all women in the U.S. House of Representatives. The Congressional Progressive Caucus (CPC) is a membership organization within the Democratic congressional caucus in the United States Congress.  The CPC is a left-leaning organization that works to advance progressive and liberal issues and positions and represents the progressive faction of the democratic party.  It was founded in 1991 and has grown steadily since then, having more recently added 20 members since 2005 and having hired its first full-time Executive Director, Bill Goold, in May of that year.  Subsequent Executive Directors have included Andrea Miller (2009–2011) and Brad Bauman (2011–2014).  With 71 members, it is currently the largest Democratic congressional caucus.
