Ted Cruz has oversight over NASA

I've read a few articles about this over the last couple of days. For example:

Ted Cruz, Longtime Foe Of NASA And Science, Will Oversee NASA And Science In New Congress

My question is: How much control will he actually have? Can he dictate what NASA focuses on or make them abandon certain projects, like climate research?



How big of a problem is this?
