Why did Nixon do during the investigation?

During the Watergate investigation, President Nixon attempted to undermine the inquiry by denying involvement and resisting subpoenas for documents and recordings. He famously ordered the firing of special prosecutor Archibald Cox in what became known as the "Saturday Night Massacre." Nixon also sought to cover up the scandal through various means, including misleading the public and obstructing justice. Ultimately, these actions contributed to his resignation in 1974 as pressure mounted for accountability.
