Cantwell has expressed support for making Plan B contraceptives available to girls 16 and under. In 2007, she cosponsored the Prevention First Act, a bill that sought to increase national access to family planning and preventative methods as a means to reduce unwanted pregnancies.[67] It included providing women with access to Plan B as well as expanding family planning to be covered under Medicaid.[67] As an advocate of increasing access to family planning and sexual health education, Cantwell argues that these venues for increased education are necessary to reduce the number of unwanted pregnancies.[68] She received criticism from her Republican challenger, State Senator Michael Baumgartner, who suggested that Cantwell was too extreme and too far to the left of most Washington voters on this issue, and expressed concern about 11-year-olds getting these drugs without a prescription.[69]
