Lindy Chamberlain's baby was killed by a dingo.
Richard Nixon was forced to resign because of the Watergate scandal, in which many other people were also involved.  It is not clear from your question which one you mean.  The journalists who mostly exposed the scandal were Woodward and Bernstein.

What did Lindy Chamberlain say when the guilty verdict was announced? "Dingo too well, did it?" (Oz joke at the time. The verdict was eventually reversed.)

Are you referring to "deep throat" who's identity was finally revealed this week as the 2nd in charge of the FBI?
Lindy and Michael Chamberlain were the Aust couple who's baby Azaria was taken by a Dingo. She was later charged with murder and he with being an accessory after the fact based on extremely dodgey forensic evidence. After serving three years Lindy was released when the baby's matinee jacket was found in the desert.
