President Donald Trump will announce his intention to move U.S. Space Command headquarters out of Colorado to Alabama on Tuesday, officials told national news outlets including The Associated Press.

Space Command has been at full operational capacity at Peterson Space Force Base in Colorado Springs since December 2023, after former President Joe Biden announced in July that year it would stay in Colorado.

Colorado officials previously expressed concern that Trump’s decision during his first presidential term to move Space Command to Huntsville, Alabama, was politically motivated, as he waited until after the 2020 election to announce the move. Alabama went for Trump, a Republican, in that election, and Colorado went for Biden, a Democrat.

Colorado officials from both parties have advocated Space Command staying in Colorado. Peterson housed a previous version of Space Command from 1985 to 2002. The Air Force subsequently oversaw military space operations from the site.

Colorado Attorney General Phil Weiser, a Democrat who is running for governor in 2026, said in a statement Tuesday his office has been preparing for legal action over a Space Command relocation if Trump “made such an unlawful decision.” Weiser said military families in El Paso County have relied on the decision to keep Space Command headquarters in Colorado.

“The Trump administration should not play political games with our nation’s military readiness and military families,” Weiser said in a statement. ”Moving Space Command Headquarters to Alabama is not only wrong for our national defense, but it’s harmful to hundreds of Space Command personnel and their families.”
