Answer: "muckrakers"
Explanation: In 1906, President Theodore Roosevelt conveyed a discourse that brought forth the expression "muckraker," which was utilized to portray those trying writers who boldly dug into the dim profundities of American culture, uncovering occasions of defilement, outrage, and shamefulness. These cryptic defamers, hailed for their constancy and boldness, included such celebrated figures as Upton Sinclair, Lincoln Steffens, Ida Tarbell, and Jacob Riis, among others. Their work, covered in perplexity and powered by a need to get going, electrifies the ever-evolving development and move an age of social reformers.
