muckraker

A journalist who investigates the scandalous activities of public officials and businesses.

The term “muckraker” was first used in a speech on April 14, 1906 by President Theodore Roosevelt: “In Bunyan’s Pilgrim’s Progress you may recall the description of the Man with the Muck-rake, the man who could look no way but downward with the muck-rake in his hands; Who was offered a celestial crown for his muck-rake, but who would neither look up nor regard the crown he was offered, but continued to rake to himself the filth of the floor.”

The most famous muckrakers in American history are probably Bob Woodward and Carl Bernstein for their work in exposing the corruption in the Nixon administration.
