Final answer:
After Nixon turned over only some Watergate tapes, which seemed tampered with, demands for all tapes increased. This led to the 'Saturday Night Massacre' and eventual release of conclusive evidence against Nixon by the U.S. Supreme Court.
Step-by-step explanation:
President Nixon's decision to turn over only partial tapes from the Watergate scandal to the special prosecutor was significant in the unfolding of the Watergate scandal. Initially, Nixon provided some tapes, which appeared to be tampered with, spurring further demands for the release of all the tapes pertaining to the investigation.
Nixon's refusal, citing executive privilege, led to the infamous "Saturday Night Massacre" where he ordered the firing of the special prosecutor, Archibald Cox. This resulted in the resignation of his attorney general and the assistant attorney general in protest.
Following this, the U.S. Supreme Court compelled him to release the actual tapes, which provided conclusive evidence of his involvement in the Watergate break-in and cover-up. These revelations fueled the impeachment proceedings and ultimately led to Nixon's resignation.
Several incidents ensued after the partial release, including intense scrutiny and a plummet in public approval for Nixon. When it became known that Nixon's own taping system had recorded his Oval Office conversations, it contradicted his claims of innocence and demonstrated efforts to interfere in the investigation. The crisis peaked when the tapes revealed Nixon's knowledge of the Watergate break-in and his attempt to use the CIA to obstruct the investigation, leading to impeachment articles and his eventual resignation on August 8, 1974.
