O que significa institutional prerogatives ?

WASHINGTON — President Trump’s legal team is wrestling with how much to cooperate with the special counsel looking into Russian election interference, an internal debate that led to an angry confrontation last week between two White House lawyers and that could shape the course of the investigation.

At the heart of the clash is an issue that has challenged multiple presidents during high-stakes Washington investigations: how to handle the demands of investigators without surrendering the institutional prerogatives of the office of the presidency. Similar conflicts during the Watergate and Monica S. Lewinsky scandals resulted in court rulings that limited a president’s right to confidentiality.
