Free Britney movement
U.S. Burgess Owens, Marjorie Taylor Greene, Andy Biggs and Matt Gaetz invited Spears to testify on her conservatorship to United States Congress. In relation to Spears' case, U.S. Senators Bob Casey Jr. and Elizabeth Warren called on the United States Department of Health and Human Services and the Department of Justice to give them data on conservatorships so they could make policy-related recommending on the system. Casey Jr. and Warren called for more federal oversight on the guardianship system in the United States after Spears' testimony. The American Civil Liberties Union (ACLU), a nonprofit organization, decided they would help Spears in dissolving the conservatorship if she requested to do so. They filed an amicus curiae to support Spears' plea to choose her own legal representation.
