The Congressional Hearing Health Caucus (Caucus), a caucus of the United States Congress, was created in 2001 in cooperation with the National Campaign for Hearing Health, a public education and advocacy project run by the Deafness Research Foundation (now called the Hearing Health Foundation.)
 The focus of the Congressional Hearing Health Caucus includes several aims that promote hearing health and encourage universal newborn hearing health screenings for all Americans.
 Those most at risk for hearing-related concerns are newborns, infants, and the elderly, particularly if such issues are left undetected.
 Therefore, a primary goal of the Congressional Hearing Health Caucus is to see that auditory abilities of all Americans are screened, including universal hearing screening for newborns.
 One of the co-founders and co-chairmen of the Caucus was former Congress Member James T. Walsh (R-NY).
 The Director of the National Campaign for Hearing Health at the time of launch of the CHHC, was Elizabeth Thorp, who had herself been born with unilateral deafness not discovered until she was eight years old.
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.
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 Blue Dog Coalition, commonly known as the Blue Dogs or Blue Dog Democrats, is a caucus of United States Congressional Representatives from the Democratic Party who identify as conservative Democrats.
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.
The Populist Caucus was a caucus within the United States House of Representatives.
 The caucus was created on February 11, 2009 by Democrat Bruce Braley of Iowa.
 The caucus included 25 members of the House, all of which are from the Democratic Party.
 The fifteen members of this caucus are also members of the Congressional Progressive Caucus.
 As of 2014 the caucus is effectively defunct.
The Congressional Israel Allies Caucus is a caucus within the US House of Representatives.
 In 2006 the group formed as the first reciprocal caucus to the Christian Allies Caucus in the Israeli Knesset called the Congressional Israel Allies Caucus (CIAC).
 The Caucus is bipartisan and led by two Democrat Co-Chairs, co-founder Rep. Eliot Engel and Rep. Brad Sherman, and two Republican Co-Chairs, co-founder Rep. Trent Franks and Rep. Doug Lamborn.
 During his time as a Representative, Vice President Mike Pence also served as a CIAC Co-Chair.
The Congressional Pro-Trade Caucus (CPTC), founded by Democratic Congressman Henry Cuellar in 2009, during the 111th Congress.
 Congressman Cuellar, a member of the coalition of Blue Dog Democrats, characterizes the group as Democrats and Republicans from all across the country, united by the belief that trade is the lifeblood of the global economy and that healthy trade is a prerequisite for economic recovery.
 One of the primary issues of interest to the group is the NAFTA-Mexican trucking dispute.
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.
