Who holds the cards?

This Vox explainer implies an imbalance of power, given the current distribution of parties in executive and legislative branches. Special prosecutor: can bring charges. Can be fired by (deputy) A.G., therefore subject to executive pressure. Independent commission: can publish findings. Cannot bring charges. Must be created by legislation, therefore can be vetoed by President. Special committee: can focus on assigned subject of investigation. Can publish findings. Cannot bring charges. Recent instances have produced unsatisfactory results.
