[Senator Kevin Cramer @SenKevinCramer]

I never tire of bringing space leaders here. After bringing Vice Chief of Space Operations Gen. Bratton to @319thRW, we received a briefing on the floor of @SemperCitiusSDA which reinforced what I’ve long said: Grand Forks is a powerhouse for America’s space mission.

It was valuable for Gen. Bratton to see the capabilities at GFAFB, especially as @POTUS plans major investments in the @USSpaceForce. What’s being built here is unmatched, and I was honored to join Gen. Bratton in highlighting the expertise and innovation coming out of Grand Forks.
