Elizabeth Holtzman, a New York Democrat, and Margaret Heckler, a Massachusetts Republican.

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.

Tamil Arasu Kazhagam: Tamil Arasu Kazhagam (Association for Tamil Autonomy) (Tamil: தமிழ் அரசு கழகம் ) was an Indian political party founded by M. P. Sivagnanam (Ma.  Po.  Si) in Tamil Nadu.  It was established as an association in 1946.  Its goals were to pressurize the Indian National Congress Government of the Madras Presidency to increase the use of Tamil in administration and education, to create an autonomous Tamil state out of a composite Madras Presidency and to soften the pro-Hindi stance of the Congress.  The association was allied with the Congress during 1946-54 and worked against the Dravidian Movement.  However, it grew closer to the Dravida Munnetra Kazhagam (DMK) over time.  During 1946-54, Sivagnanam was a member of the Congress.  He left the Congress in 1954 and turned the Tamil Arasu Kazhagam into an independent political party.  During 1957-60, it was involved in various protests over the drawing of state boundaries when Andhra Pradesh split from the composite Madras State.  It eventually became a part of DMK's electoral alliance in the 1967 assembly elections.  It was also involved in the movements to change the name of the state from Madras State to Tamil Nadu and to promote the use of Tamil over Sanskrit for conducting "Archanai" (Offerings to God) in Hindu temples.  In the 1967 elections, two candidates of the party (including Sivagnanam) were elected to the assembly contesting under DMK's "Rising Sun" Symbol.  The party was also an DMK ally in the 1971 assembly elections.  In 1972, it opposed the DMK chief minister M. Karunanidhi's decision to scrap prohibition laws and switched its allegiance to DMK's splinter group - the M. G. Ramachandran led Anna Dravida Munnetra Kazhagam (ADMK).  The party did not directly contest in elections after 1971 and Sivagnanam was nominated to the Tamil Nadu Legislative Council in 1972.  He remained as the member of the legislative council till its disbandment in 1986.  The party stopped functioning after Sivagnanam's death in 1995.
