Off the top of my head, so please feel free to verify these things, a while ago (maybe near the end of the first Trump Administration or early Biden Administration?), Alabama won the contest to have the base there. After the Supreme Court removed Roe v Wade, Alabama instituted laws that conflicted with federal regulations and rather discouraged women/families/intelligent people/moral people from wanting to move to or be there. That severely harmed the talent pool that they would be able to draw upon. Thus, the Biden Administration changed the plans to the next contender in response to the conflict and problems that Alabama Republicans manufactured for no actually good reason. This just looks like the Trump Administration is arbitrarily moving it back to support Alabama Republicans. This development is honestly unsurprising, wasteful, and undermines the agency... which are all things that are entirely in line with the Republican Party's MO, really.
