Question

why was john deans testimony against president nixon so damaging?
dean had been a lawyer for two of the watergate burglars.
dean had been an important official in the white house.
dean had been a lawyer for the democratic national committee.
dean had been involved in the burglary himself.

Explanation:

John Dean served as White House Counsel, a senior official close to Nixon. His testimony carried unique weight because he had direct, insider knowledge of the White House's involvement in covering up the Watergate scandal, making his accusations credible and deeply damaging to Nixon's administration. The other options are incorrect: he was not a lawyer for the burglars or the Democratic National Committee, and he did not participate in the burglary itself.

Answer:

B. Dean had been an important official in the White House.
