Don't they try their own?

Are you asking if Congress has the power to investigate a felony committed by a fellow member?

Congress seems to think so.

Yes, that's what I was asking. Maybe "trying their own" isn't law, maybe it's just precedent and Congress THINKS it's their right to be tried by, and protected by, "their own."
