From my Knowledge,
If the head of the executive branch e.g. (The President) were subjected to a subpoena, then they have the right to claim executive privilege to withhold information from the other branches.

</span>
<span>The Interstate Commerce Commission was created in attempt to increase control. I hope I helped:)</span>
