MINUTE ORDER (Text Entry Only) The Court has reviewed the Petition filed under 28 U.S.C. § 2241 (Doc. 1) and the related request for emergency injunctive relief (Doc. 9). Petitioner (A File #: 241-723-605) asserts that he has been detained since June 19, 2026 (Doc. 1 at 4). He does not explain his delay in seeking his request for a temporary restraining order or why despite this delay, the Court should treat the situation as an emergency. Thus, the TRO request is untimely, and it is DENIED. Local Rule 231(b). In the meantime, unless and until the Court orders otherwise, the Court ORDERS that Respondents shall not remove Petitioner from the United States nor transfer Petitioner out of this District. See F.T.C. v. Dean Foods Co., 384 U.S. 597, 604 (1966) (noting the court's "express authority under the All Writs Act to issue such temporary injunctions as may be necessary to protect its own jurisdiction"). Given the exigent circumstances, the Court finds that this order is warranted to maintain the status quo pending the hearing, to preserve the Court's jurisdiction and to preserve Petitioner's access to the Court and any subsequent order and finds that Petitioner has satisfied the factors governing the issuance of such preliminary relief. This order does not prohibit the temporary transfer of petitioner outside of the District for urgent medical care, though petitioner shall be returned to the District upon the conclusion of such care. If this occurs, Respondents SHALL ensure that Petitioner receives communications from the Court without delay signed by District Judge Jennifer L. Thurston on October 20, 2026.
