But there is that pesky separation of powers thing that makes this hard to do.
Not at all. We have a US Army officer in the White House (Vindman) colluding with a CIA Agent (Ciamarella) to illegally and politically assault a POTUS.

The ball is not in their court yet. The house cannot interfere into an active Senate investigation, and The Senate cannot interfere into an active house investigation. Same with both of those and the executive branch. Just as Trump and the executive cannot interfere in this house investigation. The Constitutional separation of powers are clear on this.
