For High Crimes and Misdemeanors, yes. Not for refusing to comply with sub-legislative demands or declarations from Congress-critters. That falls under Contempt of Congress, but I don't think that amounts to much if levered against senior Executive officials. It's been done, most recently against Eric Holder in 2012, but it did precisely jack squat. Trump might always use it as an excuse to fire Rosenstein but he doesn't need an excuse in the first place and the factors keeping him from doing so already would still be there if Rosenstein was successfully held in contempt by Congress generally.

I think both Trump and the party in general in Congress is waiting to see how the mid-term elections play before they decide whether they can move against Rosenstein or the rest of the investigation. Any hint of a "Saturday Night Massacre" before the election could easily play into the Dems hands in the Congressional elections.
