(1) Whether respondents have a cognizable cause of action to obtain review of the acting secretary of defense's compliance with a proviso in Section 8005 of the Department of Defense Appropriations Act that the secretary's authority to transfer funds internally between DOD appropriations accounts "may not be used unless for higher priority items, based on unforeseen military requirements, than those for which originally appropriated and in no case where the item for which funds are requested has been denied by the Congress"; and (2) whether in 2019 the acting secretary exceeded his statutory authority under Section 8005 by transferring approximately $2.5 billion in response to a request from the Department of Homeland Security for counterdrug assistance under 10 U.S.C. § 284, including in the form of construction of fences along the southern border of the United States.
