The answer is congressional hearings to consider impeachment of Richard Nixon.
Woodward and Bernstein's investigative reporting on the Watergate scandal played a crucial role in uncovering the extent of the political espionage and cover-up activities linked to President Richard Nixon's administration. Their work led to increased public and political pressure, which eventually resulted in congressional hearings to consider the impeachment of Nixon. These hearings were a significant step in the process that ultimately led to Nixon's resignation.
This option is incorrect. "Deep Throat," later revealed to be Mark Felt, the Associate Director of the FBI, was never arrested in connection with the Watergate scandal. His identity remained a secret until 2005, long after the events had unfolded.
While Woodward and Bernstein gained significant recognition and acclaim for their reporting, including winning the Pulitzer Prize, the question specifically asks about the direct outcomes of their coverage. Their promotions, if any, are not the primary historical consequence of their work.
This option is incorrect because Richard Nixon was never formally impeached. He resigned from the presidency on August 8, 1974, before the full House of Representatives could vote on articles of impeachment. The threat of impeachment, however, was a direct result of the investigations and hearings that followed the Watergate scandal.
