Colorado’s Attorney General promised on Tuesday to sue if the Trump administration moves Space Command headquarters from Colorado Springs to Alabama.

President Donald Trump announced the relocation of the headquarters to Huntsville, Ala., a move Republican lawmakers from that state have touted all year.

Space Command reached full operational capability in Colorado Springs during December 2023, and experts have said moving the headquarters could hurt the country’s readiness to respond to threats in space.

“The Trump administration should not play political games with our nation’s military readiness and military families. 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,” Attorney General Phil Weiser, a Democrat, said in a news release.

Weiser said his office has been preparing for the Trump’s “unlawful” decision.

Space Command headquarters employs 1,700 people across all the military service branches, according to congressional testimony.

Colorado and Alabama have been fighting over Space Command since Trump made the announcement in early 2021 that Space Command would move to Alabama. President Joe Biden reversed the decision in July 2023, saying that Space Command would stay in Colorado Springs.

On Aug. 7, 2023, Colorado politicians basked in their Space Command victory in America the Beautiful Park after facing uneven odds against Alabama on military-related congressional committees. Colorado Springs Mayor Yemi Mobolade was joined by Sens. Michael Bennet and John Hickenlooper, Gov. Jared Polis and Rep. Doug Lamborn, who has since retired, were at the celebration.
