Just last year, Texas Gov. Greg Abbott joined a bipartisan chorus of governors in denouncing a Biden administration plan they said would strip states of powers guaranteed to them under federal law.

The plan would have transferred Air National Guard units from six states to the U.S. Space Force, the newly created military branch, stoking concerns about federal overreach and the erosion of governors’ control over their own guard forces. Texas wasn’t among the affected states, but Abbott made his opposition unmistakable in an open letter to the president.

He called the plan an “intolerable threat that would set a “dangerous precedent.”

“I strongly oppose any attempt to sideline governors when it comes to their respective National Guards,” he wrote.

A year later, Abbott helped Donald Trump do just that. He said that he “fully authorized” the president’s plan to send Texas National Guard members to Illinois and Oregon to protect federal law enforcement personnel who are executing immigration laws. Those states’ governors vigorously objected, saying such action was an unnecessary escalation that interfered with state sovereignty.
