Abortion refers to the voluntary termination of a pregnancy, resulting in the death of the fetus or embryo. Abortions performed prior to the third trimester are legal in the United States, although the issue has polarized mainstream political parties. Almost all state Democratic Party platforms support abortion while almost all state Republican Party platforms oppose it.
Pro-choice groups believe that a woman should have access to whatever health care she needs and that she should have control over her own body.
