President nixon resigned from office in 1974 after he was informed that the senate would impeach him, as allowed in the constitution, for his actions in the watergate scandal. one of the key reasons that nixon’s actions became public was
a) the freedom of press guaranteed by the first amendment.
b) the right to confront witnesses as guaranteed by the sixth amendment.
c) the limitation of judicial powers as defined in article 3 of the constitution.
d) the prohibition against illegal search and seizure as guaranteed by the fourth amendment.

Explanation:

"Watergate" refers to efforts by persons working for President Nixon's reelection campaign to spy on their opponents at Democratic party headquarters, and subsequent efforts to cover up those crimes.

An insider at the FBI who remained anonymous at the time, known only as "Deep Throat," began to give information concerning Watergate to reporters Bob Woodward and Carl Bernstein of the Washington Post.   Persistent investigative reporting by Woodward and Bernstein brought the scandal to light and forced Congressional hearings.   The freedom of the press played a central role in the road to the impeachment of President Nixon.
