Gillibrand has moved her political positions and ideology toward a liberal, progressive position since her appointment to the Senate. Gillibrand was an important part of the successful campaign to repeal "Don't Ask, Don't Tell". In March 2011, Gillibrand co-sponsored the PROTECT IP Act, which would restrict access to web sites judged to be infringing copyrights. In 2013, Gillibrand proposed the unsuccessful legislation that would remove sexual assault cases from the military chain of command; the bill was cosponsored by Republican senators Rand Paul and Ted Cruz.
