an increased number of death threats after Spears's testimony. Jamie Spears also filed a petition objecting to Montgomery's request for additional security, but the petition clarified that it was "not meant in any way to minimize the threats to Ms. Montgomery", and rather was due to the substantial cost of the security. On July 10, Montgomery pushed back against Jamie's claims that she mistreated Spears as conservator, alleging that Jamie had previously used $2 million of Spears's money "to defend himself" as conservator of the estate. On July 12, Spears was reportedly in talks with attorney Mathew S. Rosengart, a former federal prosecutor, about his potential appointment as her new counsel. On July 13, the American Civil Liberties Union filed an amicus brief in the case, in support of Spears's wish to choose her own attorney. The brief was filed alongside other 25 civil and disability organizations. In a July 14 hearing, Judge Penny approved the resignations of Bessemer Trust and attorney Sam Ingham. The court also granted Spears the right to select her own attorney, Mathew Rosengart. Rosengart informed the court that he would be working to terminate the conservatorship. Spears spoke in the hearing, reportedly breaking down in tears when she described further abuses under the conservatorship. Spears called the alleged mistreatment "cruelty", and claimed that she "thought they were trying to kill [her]". Spears said she wanted her father removed as conservator, and that she intends to charge him with conservatorship abuse. Later that day, Spears publicly endorsed the #FreeBritney movement for the first time, using the hashtag in a caption on an Instagram post. Spears said that she felt "blessed" after earning "real representation", referring to Judge Penny's decision to allow her to choose her own counsel. On July 26, Rosengart filed a petition seeking to remove Jamie as conservator of Spears's estate and to replace him with Jason Rubin, a CPA at Certified Strategies Inc. in Woodland Hills, California. The petition made several claims of mismanagement against Jamie, namely money laundering his daughter's earnings and signing contracts on her behalf. The petition also included declarations of support from Montgomery and Lynne. The former stated in behalf of Spears's medical team that it is in her health's best interest to withdraw Jamie from overseeing her estate. The latter disclosed that Jamie hired a sports enhancement doctor, whom he encouraged to prescribe lithium to their daughter. Lynne
