MONTGOMERY – Alabama Attorney General Steve Marshall has filed an amicus brief in the U.S. District Court for the District of Colorado urging a federal judge to dismiss a lawsuit filed by the State of Colorado challenging President Donald Trump’s decision to permanently locate U.S. Space Command headquarters at Redstone Arsenal in Huntsville.

Marshall announced the filing Thursday, arguing that Colorado’s lawsuit improperly seeks to overturn a decision made by the President as Commander in Chief regarding the location of a major military command.

“Colorado is asking a federal court to override the Commander in Chief on a national security decision because they don’t like the outcome. That’s not a legal argument, it’s sore loser politics dressed up in a lawsuit,” Marshall said in a statement.

He added that while the Biden administration had previously reversed the original decision, Alabama has continued to support executive authority over the matter.

“Despite Biden’s failed attempt at playing politics, we recognize and respect executive decision making, not legal delays of our country’s national security. It’s time for Colorado to respect the same principle now that the final decision has been made,” Marshall said.

The dispute over the permanent headquarters for U.S. Space Command dates back to 2019, when the U.S. Air Force began a nationwide search for a permanent location. Following a multi-phase evaluation, the Air Force identified Redstone Arsenal in Huntsville as the preferred site based on mission capability, projected cost savings, and other site selection criteria.

In January 2021, President Trump accepted the Air Force’s recommendation and designated Huntsville as the permanent headquarters.

After President Joe Biden took office, his administration ordered a new review of the decision. According to the Attorney General’s Office, that reevaluation, completed in late 2022, again identified Huntsville as the Air Force’s preferred location.

However, in July 2023, President Biden selected Colorado Springs, Colorado, as the permanent headquarters. The Attorney General’s Office said the White House declined to explain the decision to investigators from the Government Accountability Office and the Department of Defense Inspector General, citing presidential decision-making authority.

Marshall’s office also referenced media reports published at the time indicating the decision was influenced by opposition to Alabama’s abortion law, including an NBC News report quoting an administration official as saying, “This is all about abortion politics.”

Following his return to office, President Trump redesignated Redstone Arsenal as the permanent headquarters for U.S. Space Command on Sept. 2, 2025.

Colorado subsequently filed suit in federal court seeking to overturn that decision. Alabama’s amicus brief asks the court to dismiss the lawsuit, arguing that the President acted within his lawful authority in selecting the headquarters location.

The case remains pending before the U.S. District Court for the District of Colorado.
