Answer:
Muckrakers
Explanation:
In the first decades of the twentieth century, Theodore Roosevelt coined the term muckrakers to describe writers who agitated for change by targeting powerful political and industrial people and institutions.
The muckrakers were reform-minded journalists who exposed established institutions and leaders as corrupt. Since they had large audiences and followers in popular journals and magazines, they find corruption in industries and expose it to the public.
