Final answer:
The question about the resignation accepted with regret could refer to multiple instances in American political history, but lacks a clear subject without additional context. Notable examples include the Iran-Contra affair and the Watergate scandal.
Step-by-step explanation:
Resignations and Political Aftermath
The resignation referred to in your question might relate to multiple historical figures, but without a specific name like Poindexter, we cannot be certain. However, in the context of resignations during American political scandals, a notable instance was the Iran-Contra affair during Ronald Reagan's presidency. Several officials resigned due to their involvement, and some, like Marine Lieutenant Colonel Oliver North, were fired. Subsequently, most officials involved were granted immunity for their testimonies, or their convictions were pardoned by President George H. W. Bush. Another significant event was the Watergate scandal, where President Nixon ultimately resigned on August 8, 1974, an action that was followed by a pardon from his successor, President Gerald Ford.
