Answer:
Political cartoonist Thomas Nast worked to expose the illegal activities of New York City's "Boss" Tweed .
Step-by-step explanation:
Thomas Nast was an illustrator and cartoonist. He created the elephant used as the Republican Party's emblem and one of the best-known images of Santa's appearance. The donkey used as a Democrat emblem also became known for his drawings. Nast also made paintings and book illustrations, but is primarily remembered for his impressive cartoons.
Nast made his most famous cartoons in the 1870s when he attacked corrupt New York politician William M. Tweed and the political machinery known as Tammany Hall under his leadership. His drawing “Tammany Tiger Loose” made the raging tiger a permanent symbol of Tammany Hall. Nast's drawings are thought to have contributed significantly to the collapse of Tweed's machinery and to the identification and capture of Tweed fleeing from Spain in 1876.
