Colorado Attorney General Phil Weiser filed a federal lawsuit Wednesday challenging President Trump’s decision to relocate U.S. Space Command headquarters from Colorado Springs to Huntsville, Alabama, arguing the move amounts to unconstitutional retaliation against Colorado’s mail-in voting system.
The lawsuit, filed in U.S. District Court for Colorado, seeks to block the transfer and obtain a judicial declaration that the president’s decision violates constitutional limits on executive power. Weiser said the action was necessary to defend Colorado and other states from “further pressure or punishment unless they give up their constitutional authority” over elections.
“The Constitution does not permit the Executive Branch to punish or retaliate against states for lawfully exercising powers reserved for them, such as the power to regulate elections,” Weiser stated.
President Trump announced the relocation last month during a White House event, saying, “The problem I have with Colorado, one of the big problems, they do mail-in voting… So that played a big factor also.”
Space Command, created by Trump during his first term alongside the U.S. Space Force, has operated from Peterson Space Force Base in Colorado Springs since its reestablishment in 2019. The planned move would shift the headquarters to Huntsville, home to major NASA facilities and missile development programs.
Weiser’s office is engaged in multiple lawsuits against the Trump administration, including challenges to decisions ending billions in electric-vehicle infrastructure funding and pausing new wind energy leases.
