In a letter to President Biden, Abbott, who has clashed with the commander in chief on a number of matters, said the proposal is an "intolerable threat" to the National Guard.
"That proposal would give the Secretary of the Air Force unilateral authority to transfer Air National Guard units to the Space Force — without first obtaining gubernatorial consent," Abbott wrote in the May 3 letter.
On Monday, he called it a "power grab."
The Republican governor argued the measure would sideline governors as the commanders in chief of the National Guard in each state and U.S. territory.
